Rigging a character for Unreal Engine with Blender, Rigify and Uefy 2

[@RakizFarooq]

IMPORTANT: In new versions the Preprocess functionality has been automated away. Wherever your see instruction to click on preprocess skip ahead to Build Skeleton. Updated instructions for importing to UE5 can be found at kzbin.info/www/bejne/fZWyk3qcnbeDfaM Full Playlist: kzbin.info/www/bejne/bJ3Ei3mXqq-ciKM

[@RakizFarooq]

If your character is just a static mesh with no bones at all. You can still rig it with this process. Make sure Rigify addon is enabled and just do Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton in object mode to get a prebuilt skeleton into the scene. Position the bones into your mesh to match it's pose. Then you need to attach the mesh to this skeleton and weight paint it. This skeleton will already have correct names and rolls. So just continue from 14:21 in this video to pose the character and carry on.

[@samohickey]

Awesome! Thank you so much! :D

[@RakizFarooq]

Make sure you have Rigify and FBX support enabled in Edit -> Preferences -> Addons before you import any skeletons from the Uefy Script armature menu.

[@AJPanameno]

@@RakizFarooq beautifull! I was cofused about this step, I will try it right now!

[@linnexmiles]

After you have performed the steps of Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton, please advise on best practice when you instruct to attach the static mesh to and weight paint the prebuilt skeleton. Will just parenting the mesh to the prebuilt skeleton and applying Armature Deform with Automatic Weights will suffice???

[@RakizFarooq]

Automatic weight painting is pretty decent and will get your character moving. But automatic weight paint needs manual adjustment and you will need to use Blender's weight painting tools to improve it. I typically load Paragon assets and look at how the weight paint is handled on different parts of the mesh. It is awesome to have actual AAA quality game characters as reference to update your own weight paint. Blender has some nice tools for the job. You will need to look into that.

[@RakizFarooq]

UPDATE: Uefy v2.5 Released! Adds support for Unreal Engine 5 ! You will still use this tutorial to rig characters for UE5 as the process is the same with a few more options for spine and hand bones. Importing to the engine and retargeting is a little different. You can check tutorials in the channel playlist on how to do that. kzbin.info/www/bejne/d5nTgKWnrqyZZtE

[@RakizFarooq]

UPDATE: Around 33:30 in the video I mention clicking on layers to make the deform bones visible. In Blender 4.0 and above the layers panel has been replaced by Bone Collections panel. Use the eye icon on Uefy Body, Uefy Face and Uefy IK collections to turn them on/off. It has the same effect as layers but everything is properly named.

[@RakizFarooq]

UPDATE: Uefy 2.1 Released! The preprocess functionality has been automated away. Wherever your see instruction to click on preprocess skip ahead to Build Skeleton. Also added animation editing features. kzbin.info/www/bejne/sF6xgXaeZZZ3rac Uefy 2.1 is a free update. Use your existing emailed download link to get the latest file.

[@stevens3d]

Thanks for these videos! Isn't there a simple video that shows how to create an animation on blender with Uefy and export it to unreal engine with the right skeletal mesh UE5 or UE4 mannequin?

[@BatheswithToasters]

This is an outstanding tool. Following your tutorials, I was able to successfully import and re-target animations for a basic rig. Works like a charm, thanks Rakiz!

[@CrossPadCastle1]

my mesh wont follow the generated rig I'm stuck at 28:26 It only works with Automatic weights, is that a problem my character follow when I do the automatic weights.

[@RakizFarooq]

The addon works by transferring existing weight paint from the original character skeleton to the final rig. Either you never had any starting weight paint or you did not setup the json file correctly. If you don't have original weights then you need to add them yourself. You start with automatic weights and make updates as necessary.

[@theoadamsiv7844]

This is an excellent product. I was stuck for days trying to get some troublesome meshes to work with my game, which relies heavily on ALS. I was bashing my head into a wall for weeks and freelancers didn't want to take the gig because of how niche it was. This saved my ass. Thank you. Thank you. Thank you.

[@theoadamsiv7844]

Also, if anyone who got this script addon and is having issues with it, so far I've used it to re-rig 14+ problematic meshes. Keep following the video tutorial. One mesh at a time, rewatching and referencing. Follow all the steps. If, for example, you hit one of the buttons and something isnt working, like an armature isn't parenting-- you probably skipped a step on accident. You have to make sure the right names are listed in the Uefy Script Panel. You can do it! I got the rhythm down to about 15-20 minutes.

[@RakizFarooq]

UPDATE: Uefy v2.6.0 Released. Brings compatibility with Blender 4.0 and above.

[@RakizFarooq]

Once you have gone through this tutorial. How to add extra bones to the character for armor and items is shown in this video kzbin.info/www/bejne/rGm4l4tsZ7iff5I . Where we rig the Lava Knight character from epic's Elemental Demo.

[@CrossPadCastle1]

10:03 what about extra bones? my miximo character has a bone called HeadTop_End and the mannequin doesn't what happens when you have a rig with an extra bone?

[@CrossPadCastle1]

nvm you answered this in some one else comment.

[@RakizFarooq]

You can add extra bones as shown in ( kzbin.info/www/bejne/rGm4l4tsZ7iff5I ). I should also point out that sometimes character armatures may contain 'leaf bones' that don't actually do anything and are not needed in Blender though other software makes use of them for cosmetic/display purposes. HeadTop_End is most likely an example of a leaf bone that has no weight attached to it. If you can confirm this then just ignore it or delete the bone entirely.

[@CrossPadCastle1]

thank you

Hi, when i press "build skeleton", i get a message "IK FAILED: A bone required for IK setup was missing". i used "basic pose skeleton", uefy 2.3, Blender 3.1.2

[@RakizFarooq]

If you have a static mesh with no starting bones. You can weight paint it to the basic posing skeleton. It will act as the initial character skeleton, it is not a metarig. After weight painting you must follow all of the steps from the start of the video. You are getting this message because you did not setup your metarig correctly.

[@RakizFarooq]

UPDATE: Uefy v2.1.2 Released! This is a maintenance update. If you are using Blender 2.90 and get errors on generating the metarig from the popup menu. Upgrading to this version will solve the issue.

[@TwistedIncProductions]

does this work with Character creator 3 skeletons and how would I go about setting it up

[@RakizFarooq]

I don't have any reallusion product so can't give specifics. But as I understand it they make heavy use of shapekeys. Blender doesn't allow applying modifiers to meshes with shapekeys. There are way to get around this but it is not an easy process and may require more scripts. Other than that as long the character is given a basic skeleton that corresponds to the mannequin like 6 bone spine, 2 bone limbs etc you can rig a character from any source.

[@RakizFarooq]

Uefy v2.2 has added better support for Character Creator 3 meshes ( kzbin.info/www/bejne/eHPCk6Gfjt90esU ). It is a free update you can get the latest file using you existing emailed download link.

You might have more than one mesh attached to the armature. Make sure you remove shapekeys on all meshes.

@@RakizFarooq oh so If I were attaching a new metarig to a mesh that never had a skeleton, is it a different step?

[@RakizFarooq]

You want to add an initial skeleton to your mesh and weight paint it before you start using the addon. In Object Mode you can do Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton to add a prebuilt skeleton into the scene. Move/Rotate those bones inside your mesh in Edit Mode. You can attach the armature to your mesh with Ctrl + P (Automatic Weights). Then use blender's weight painting tools to improve the weight painting. Once that is done you have a character that can be rigged by following this tutorial.

[@abrahambrookes1927]

I'm creating a goblin character that is still a biped, but is much smaller than the mannequin - how do I use this process to rig a smaller character, just move the bones to match like you do at 40:10? For clarity, the neck bone of my goblin character is at about the hips bone of the mannequin

[@RakizFarooq]

The size of the character relative to the mannequin does not matter. It just needs a similar basic bone structure like 6 bone spine etc. You follow the same process as shown in the video. Around 23:20 in this video I bring in the metarig and scale it roughly to the match the shoulders. You can do the same for your smaller character.

[@xdeschenes]

Hi, I wrote you on the other video yesterday, I am now following this tutorial as you said, my character has only 3 fingers and 2 links by fingers, when I Click on Fix Metarig at 24:00m the rig fits all in my skeleton but the 3 tips of the fingers that have only 2 links do not align and there is 2 fingers left behind unaligned. Do I deletye those? or leave them as is? thanks so much. :)

[@RakizFarooq]

Rigify metarig types must be added or deleted as a whole part. For example the fingers consists of 'limbs.super_finger' type which has 3 bones. So you must remove the entire sample by deleting all 3 finger bones. You can't remove just one or two. If you require a finger that has only two bones then you should use another type. For example you can add a 'limbs.simple_tentacle' that has 2 bones and use that as a finger. You can check the advanced tutorial to see how to add rigify types to the metarig. ( kzbin.info/www/bejne/rGm4l4tsZ7iff5I ) Alternatively a simple solution would be to just leave the 3 bone finger as is and just not weight paint any mesh to the unwanted bones.

[@Edwardmjhanrahan]

After I hit "magic rolls" (or if I manually adjust the rolls on the spine chain), and generate the rigify rig....the Hip and the Chest spline controllers are created on an angle (varies depending on the exact roll values for the spine bones). I'm not sure if I need to "apply the bone rolls" like a transform? both controls APPEAR to operate correctly, I'm just wondering why I'm seeing this \ will there be unexpected issues down the road?

[@trebands7780]

i get the following error 'Spine.004': Cannot connect chain - bone position is disjoint. incorrect armature for type 'chain _rigs' please help i followed every step i noticed these bones are not connected like the other spine ones but how do i fix this?

[@RakizFarooq]

Newer versions of Rigify allow a space between the neck and spine bones. But you have to set an additional option on the metarig. Select Spine.004 in Pose mode and turn off “Connect Chain” in Bone Properties -> Rigify Type -> Options. See image on Advanced Spine and Neck Joints section at the bottom of www.rakiz.com/blender-2-83-lts-and-uefy-script/

I got a problem, on my left hand, i have to vertex who doesn't move with the rest of the hand, like they are not weighted, but the problem is they are correctly weighted, i dont know how to fix it.

[@RakizFarooq]

In edit mode select the misbehaving vertex and see which bones are affecting it in Vertex Weights panel in the 'Item' tab. Probably it has weights for non-deform bones that was not exported like hand or foot controllers. When that happens it looks ok in Blender but shows as a problem in the editor. Remove any unwanted weights, you can compare with surrounding vertices that behave correctly to see what went wrong.

Sorry, I know this video is fairly old by this point but I'm having a strange issue. Everything in the tutorial seemed to go fine until the importing. I imported my character with the updated ue4 rolls and selected the ue4_mannequin skeleton. There were no errors during or after the import but the animations are completely jacked. He's folded in half and floating. Any ideas? Thanks :D

[@RakizFarooq]

Following the tutorial gives me consistent working results. You've likely used an incorrect skeleton or missed something else.

[@agnieszkagorowska9439]

Did you managed to fix this? Same issue here

[@ChaseTheVase]

So here's a weird one for you. I can get my character into UE4 fine, but he's 100 times too small. I've tried scaling by 100 when importing in until he is animated. After that he's tiny again until he stops animating. Neither of my two versions, normal or UE Mannequin Rolls show up for retargeting animations. I also redid the whole process skipping the 0.01 unit scale step only to have the same result. Any idea why this may be happening?

[@RakizFarooq]

This happens if the scale on your mesh or armature is not set correctly. You have to scale the mesh and armature objects independently and also make sure to apply all transforms on both of those objects. At the start of the project set unit scale to 0.01 and immediately import the ue4 mannequin into the scene. Now when you import your character it's size needs to be correct relative to the mannequin. Use the 'extract mesh' tool to separate the mesh and armature objects. If your imported character is towering above the mannequin or tiny between it's feet then you need to resize the character. Resize and 'apply all transforms' on both mesh and armature objects while they are separated.

[@ChaseTheVase]

Hi. I have a question. Is it possible to just throw a clothed and human body, boneless and non-animated character into an unreal engine and integrate the bones and movements of a third person character into it? Can you suggest a source that explains this?

[@RakizFarooq]

The character must have an armature (skeleton) for it work with unreal. In this video kzbin.info/www/bejne/g4PLdXeYipWtmqc I show how to add an armature to a static mesh but you will still need to add/fix weight painting yourself. Alternatively you can use something like mixamo to automatically add an armature to a character and then export it to uneal. But the results are often not very good, you still end up manually fixing things. There are also products like reallusion cc3 and daz3d to generate characters you can use without too much editing.

Thanks for any and all help

[@RakizFarooq]

Clothing is just another mesh you can add additional bones to the armature or shapekeys to the mesh itself to animate just like any other part of the character's body. If you are very new to blender I suggest getting familiar with rigging regular characters before you move onto clothing it is just the same process.

[@ruslanzaripov3775]

Hello! Does this mean that my custom character should already have custom armature and weight paint? In all tutorials your characters are already have armature as a starting point, but where that armature came from?

[@RakizFarooq]

If you have only a static mesh you will need to add your own initial basic skeleton and weight paint. An example can be seen in kzbin.info/www/bejne/g4PLdXeYipWtmqc for the old version. For Uefy 2 you don't need to create the whole skeleton yourself. Go to object mode Shift + A -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton. This will give you a prebuilt skeleton you can position in your mesh and weight paint. Alternatively you can use meshes from character generator programs or marketplaces which already have a basic skeleton.

@@RakizFarooq But It should have been nice to have a tutorial like this, and explain to people. Because most of us, we create the characters, and we just need a way to import them in UE4. I feel really confused with all these videos, that all start with existing armatures!

Thanks for this. This is definitely something I want to do but looks really hard (lots of steps :) ). If I have a mesh that has an existing skeleton, is it best to use that or should I rather be using something like Maximo to auto-rig a skeleton and then follow this tutorial from there?

[@RakizFarooq]

You should use the existing skeleton if it is similar to the UE4 or UE5 mannequins. Otherwise Uefy also provides a Basic Posing Skeleton. You can use Blender's built in tools to auto weight paint and manually fix any issues.

[@samskelton5501]

Hi Rakiz -- Had a question; when I click 'Build Skeleton' in Uefy, the armature then doesn't affect the character. ie. Moving any of the bones in pose mode doesn't move the mesh. It works fine before clicking Build Skeleton, but it seems like something breaks when I hit the button...

[@RakizFarooq]

The 'Build Skeleton' action will move the weight paint from the original character skeleton to the final export rig. In order to do that you must have followed all the steps shown in the video and did proper bone renaming before applying rigify. If the final built rig is not moving the mesh then it is a bone naming issue.

For static mesh characters (no bones at all) go in to Object mode Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton.

[@HaselnussWaffel]

Hello Rakiz! I'm thinking of purchasing this, it really does look incredibly useful. Quite the complex pipeline. Great job, well done! However, I have a couple of questions if you don't mind. I'd like to base the skeleton off of the "new" UE5 versions, because I'm thinking if this is where Epic is going, then probably best to stick with that. But in that case you can only like half-follow the steps shown here, is that correct? For example: Say I have a custom character with no skeleton. Following what I read in the comments here, I would add a basic pose skeleton, skin my mesh to it. But then when you A-pose the mesh + basic pose skeleton automatically (to match UE4 pose super closely), the pose is UE4 Mannequin, which is not the same pose as UE5 Quinn / Manny. Would I basically have to manually add a UE5 Quinn and eyeball the bone positions? Or when the MetaRig is added. I read in the comments that you can include Metacarpal bones and extra spine bone. Great, but then again you press a button to pose the MetaRig, which is not a UE5 pose. So I take it you'd have to manually match the MetaRig to the previously posed skeleton? But the previously posed skeleton doesn't have the Metacarpal bones or extra spine bones. Etc. I guess I'm currently slightly confused how this workflow would work to get a really precise result for good retargeting inside UE5. Seems to me like one would have to kind of eyeball bone positions to a certain extend. Thank you!

[@RakizFarooq]

For rigging UE5 custom characters we only really do two things different. We would import the Unreal Engine 5 mannequin instead of the UE4 manny. The new version of the addon will correctly pose both the character and metarig according the new UE5 mannequin pose. Secondly before clicking on "Fix Metarig" we have the option to specify how many bones to add to the spine/neck plus to keep the metacarpals in the hands or not. The rest of the process follows exactly as shown in this tutorial. However import to Unreal Engine 5 and retargeting requires some additional work by setting up a couple of Rig related UE5 objects inside the editor. You can check that pipeline by following the links in the description of kzbin.info/www/bejne/d5nTgKWnrqyZZtE

[@HaselnussWaffel]

@@RakizFarooq Sooo, bought the addon, great stuff! And understood, thank you! That's awesome. So it poses to whatever you specify in Properties: UE Mannequin, that's so smart. I thought the pose was like hard-coded or something (basically always UE4 Mannequin). Question, though: When you create the final rig based on the MetaRig, the new bones (e.g. spine) don't seem to be weighted. Basically rendering all that elaborate weight painting at an earlier stage (When adding the Basic Pose skeleton) somewhat useless. I mean yes, the weight painting in that stage needs to be done properly to get the character into UE5 Quinn pose; But then you basically have to do it again on the Epic skeleton towards the end of the pipeline, is that correct?

[@RakizFarooq]

No.. If you follow the procedure as shown in the tutorial the original weights of the initial character are transferred to the final rigged character ready for export.

[@HaselnussWaffel]

@@RakizFarooq thanks again for the reply! Oh, I have to go through it again then. How can the weights be properly transferred though, if the bones don’t even exist on the initial character? Like the basic pose skeleton doesn’t have metacarpals or the extra spine bones that the UE5 manny has. However, the metaRig does. Are the weights just averaged divided up between the additional bones? On that note, when I pose the metaRig (like ->fix metaRig -> pose metarig), the metacarpals are left behind. That’s expected? Basic pose skeleton only has 1 hand bone, so I guess that would make sense. Thanks Rakiz, will try again.

[@RakizFarooq]

The addon only transfers weights for bones that exist in the initial skeleton. The Basic Posing Skeleton is only an example. If you need more bones like metacarpals or twists you can add them and weight paint them before starting rigging. You can also do Shift + A -> Armatures -> Uefy Script -> Reference Skeleton -> UE5 Manny 89 Proxy (A-pose) and use that as your initial skeleton instead of the Basic Posing one. It has all the default metacarpals and twists that you will need to weight paint. You can also add additional bones not in the Mannequin skeletons. There are rules for doing that as described in kzbin.info/www/bejne/pWOmg2yQrcekZsU and also shown in the advanced tutorial at kzbin.info/www/bejne/rGm4l4tsZ7iff5I

Hi! I have a problem with exported armature. Everything works fine except axeses of exported skeleton looks completely different compared to original ue mannequin, so i can't use cool stuff like procedural IK for legs in game, cause armature axes is not correct and not even strait like ue mannequin. Is it suppose to be like that or i made something wrong? Because character skeleton axes back in blender setupped correct

[@RakizFarooq]

I have used IK setups in my projects with characters rigged as shown in the video many times without any issues. The default way to use the addon is to create character that will be imported to Unreal with a 'new' skeleton. It will have bone axis based on the Blender standard. Which is what I want as Blender is my main digital content creation application. If you want to characters with bone axis the same as the Original UE Mannequin you use the second export as shown in 34:25 using the 'UE Mannequin Rolls' operator. You can also review the video on rigging the mannequin in kzbin.info/www/bejne/bnLHZaltrZlkiKM where I talk more about the differences between the two exported files with Blender based bone axis and with Unreal Original Mannequin based bone axis.

I heared i could use the constrains, but the old rig and the ue4 skel have different bone orientations. would that still work?

[@RakizFarooq]

You can do that if you are experienced with Blender animation workflow. But mostly Uefy is designed for character rigging and creating new animations rather than converting old ones. If you want just want to retarget old existing animations. You are better off doing this directly in UE5.

[@RDD87z]

@@RakizFarooq yes the thing is if i do this directly in ue5, it will take some performance specially if you do this for all the characters on screen... my plan was to do the retarget in blender then bake the animation on the ue4 mannequin.

[@RakizFarooq]

You can do the same in UE5, retarget and create baked animations in the editor. These final baked anims can then be used directly without any real time retargeting. You also get added benefit by advanced key compression algorithms built into the editor. The better solution for this is the UE5 editor.

If the bone is rotating but the mesh is not then it is a weight issue. Additionally in Rigify rotating the hand will auto-rotate the lower twist bone in the lower arm. Not the lower arm bone itself.

Hi! Thanks for your awesome tutorial (1 year ago) I have a question I hope you can answer... How do I do to keep the facial bones with mesh weights and then export it to unreal in order to keep the skeleton compatible with the UE4 mannequin???

[@RakizFarooq]

For simple and easy to manage jaw or eye movement you can add a few extra bones to the face as shown in kzbin.info/www/bejne/rGm4l4tsZ7iff5I this is enough in most cases. For a full fledged face rig you can use 'face.super_face' as shown in kzbin.info/www/bejne/o3u4iH2ud9-Kabs

[@NotAnIlluminatiSpy]

One thing that is annoying me currently is how many models I have using a ue4 sk mesh that haven't been updated to use the new 5 spine version. Am I right in thinking that this tool(2.5) would let me export to blender, rip out the current skel and slap in the new Manny/Quinn sk in the manner shown in this video? on any mesh I have using ue4 skel?

[@RakizFarooq]

No .. even though it is something you could do with Uefy. That is not what the tool is for and you will need to add weight paint for the missing bones in the original skeleton. More importantly why would you want to convert UE4 characters to a UE5 skeleton anyway? It offers no benefit. The animation retargeting system in Unreal Engine 5 lets you use any kind of skeleton with relative ease.

[@NotAnIlluminatiSpy]

@@RakizFarooq I know the anims can be retargetted easily enough through the ikrt tools (and honestly, with much better results than 4.27) but I have other plugins that essentially don't work as well without the 5 spine sk version. They deal with warping, and other new functions of the anim BP they claim only work/work better with Manny. I don't understand it at all, so you might be right, I'm only regurgitating what I've been told so I couldn't tell you either way. Thanks for the speedy reply, though.

[@RakizFarooq]

You may be correct about using other plugins. I tend to write my own code so this is not an issue for me. If you want to convert a UE4 skeleton to a UE5 skeleton you will need to provide weight paint for all the new bones in the spine/hands/twists etc using built in skinning tools of Blender.

Hi, thanks for the great work brother. One question: i imported a model from character creator 4 and whe i try to extract mesh it errors "...skipped because it has shape keys" how can i fix this?

[@RakizFarooq]

The extract tool can not work on any mesh with shapekeys because of restrictions imposed by Blender itself. You need to delete the shapekeys on the mesh. The tutorial for CC3 is at kzbin.info/www/bejne/eHPCk6Gfjt90esU There is a way to delete the shapekeys, rig the mesh and copy them back later. But only for portions of the mesh whose pose is not changed during the rigging process. So you can use this to recover shapekeys for the face or even for the whole character if you don't change the pose. You can review the tutorial rigging the Daz3d character where I use this method kzbin.info/www/bejne/jX3NhqB8f5yljq8 If you are new to rigging it would be easier to just the delete the shapekeys and leave it at that. You can create any new ones after the rig is built and they will work just fine.

Normally I would rig this type of character in Free Form mode with proper animal type limb like in kzbin.info/www/bejne/sF6xgXaeZZZ3rac .

[@RakizFarooq]

In object mode use Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton to bring a prebuilt skeleton into the scene. You can Rotate/Position it into your mesh and weight paint it. This will act as your character's skeleton afterwards it is just following this tutorial from the start.

[@RakizFarooq]

I didn't publish a video on weight painting but you can review how to do automatic weight paint around 26 min into kzbin.info/www/bejne/g4PLdXeYipWtmqc However automatic weight painting is not enough and you need to use Blender's built in weight tools to update the weight paint until it is satisfactory. However you don't need to build the skeleton yourself like in that video just use the prebuilt one as suggested in previous comment.

[@davidtaylor8195]

I imported this 3d model with the exact same settings, but all the armature bones are pointing straight up. Anyone know why? thanks

[@RakizFarooq]

The software and options used to make the model may not work well with Blender's version of fbx importer. Select different import options like "Automatic Bone Orientation" with/without "Force Connect Children" to get the optimal import. What you want is to have all the bones point towards each other. Sometimes the best you get is a partial result where few bones must be fixed manually.

[@RakizFarooq]

It seems a fresh download from mixamo of the same character imports differently to the older version of the file. I guess they changed something. In any case import the character as suggested in the above comment and manually fix any bones that need it as shown in kzbin.info/www/bejne/rGm4l4tsZ7iff5I around 7min 45s onward.

Doing some initial work on the original armature allows us to pose the mesh to the Epic A-pose. It allows us to snap the metarig limbs and fingers near perfectly without manual work. It also makes it easier to transfer the original weight paint to the finished rig.

'root' is just the name of the UE4 mannequin armature object. If your UE Mannequin is not called root then either you have a naming collision, where another object is already called root.

If you created a json file for renaming bones of your original character make sure the entries for the feet are set correctly to "foot_l" and "foot_r". Also make sure there are not any other misnamed bones. These are case sensitive names, all of them must be correct. Review all the bone names of your character original unrigged skeleton after running the json file. They should match the hierarchy in the Unreal Mannequin. Other that I can't think of anything else.

This is a requirement from Rigify addon. You can still get around this requirement. Once your character is ready for export. You can select the layer with the Uefy built export chain and turn of the 'deform' flag for any finger bones you don't want. This will prevent them from being exported.

You can check kzbin.info/www/bejne/g4PLdXeYipWtmqc around 39 min 20 sec mark on how to select the correct layer. Then you can update the weight paint for only those bones. Be careful to avoid putting any weight on the IK bones or any of the rigify control or mechanism bones.

[@asdfewagasdfzxcvasd816]

If you have existing animations for your initial skeleton but with the wrong bone roles/initial position does this keep/fix your animations or is this just for the initial skeleton setup and should be done before you make any animations?

[@RakizFarooq]

This process is not to edit existing animations but rather to create new ones. However if your existing animations were made for Rigify controls then those should still work.

[@RakizFarooq]

I suppose the last reply should be updated. With the release of Uefy 2.1 you can now import existing animations from Unreal Engine and apply them to your character in Blender. kzbin.info/www/bejne/sF6xgXaeZZZ3rac

[@trebands7780]

what do i do with the extra parts on the mixamo character IE Top Head Thumb 4 ect.

[@RakizFarooq]

If they do not have any weight paint, you can safely ignore them. When you import your character you can also select "Ignore Leaf Bones" in Armature options to not bring in these extra bones in the first place. Beware to only select this option for characters that have extra bones at the end otherwise you'll lose actual deform bones.

I'm having a lot of problems going by this to rig a character with a metarig for UE5.

[@RakizFarooq]

Enable checkbox on "Keep Metacarpals" and set Spine to "6 spine 2 neck 1 head UE5" Do this "before" clicking on "Fix Metarig"! That is the only real change to rigging for UE4 vs UE5. Everything else can remain at default values or as shown in the video.

[@DesignsbyDonBrown]

I watched the "Rigify to UE with optimized animation rig" video and got it to where I can see the generated rig and skeleton, but when I do the armature deform they don't animate the character.

[@RakizFarooq]

Did you start with a static mesh? Meaning your character did not have any original skeleton or weight paint? Or did your character have an original skeleton that could move it around.

[@DesignsbyDonBrown]

It's a character from "makehuman", that I exported from the software without an armature and added a metarig with this tutorial using Uefy

[@RakizFarooq]

That is not what I asked. I am going to assume you started out with just a static mesh. Building a metarig is not going to make it move. You need to construct an initial skeleton and weight paint the mesh to those bones. Blender has built in tools to do this. Then you can use Uefy to create a game engine compatible rigify rig for export. An example of rigging a static mesh is in kzbin.info/www/bejne/g4PLdXeYipWtmqc Unlike that video, in object mode you can use Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton to construct an initial skeleton and move/rotate it into you mesh. You don't need to construct it one bone at a time. You do however need to use Blender to weight paint your mesh. Only a brief example of an Automatic Weight Paint is provided around 26 mins in that video. Automatic Weight Paint is not good enough you will need to use Blender's weight painting tools to manually fix it. If you don't know how to do that or can't figure it out then I suggest you get characters that already have weights done for them. Either from a marketplace or from character generators like CC3 or Daz3d. Once you have a character with an initial skeleton and weight paint you can follow this tutorial to create the final rig.

[@biomatrix1-159]

Hi, I’m new to making character rigs. While using Uefy, I’ve tried to follow along with the tutorials, only to fall short. I’m writing this in hopes of someone answering, and maybe that’ll help me better than watching a video. The character I’m trying to rig is one I made for UE4, in T-pose. The mesh has a double mesh, which is intended to make a stylized outline around the character. After I move the basic human rig in place and made the fingers, I then parent the mesh to the rig with automatic weights. What happens is the mesh underneath working just fine, while the outline mesh doesn’t get weighted. And trying to manually paint the skin weights for the outline mesh has proven almost impossible. Is there a workaround for such a character mesh?

[@RakizFarooq]

Sounds like you are using automatic weights for only one mesh. You could select your second mesh, shift click the armature and use Ctrl+P to use automatic weight again. Alternatively I believe there are tools in blender to project weights from one mesh to another. In any case this is probably not going to give you workable results. Automatic weight painting is a good starting point but you will need to make a lot of manual updates to both of your meshes. Depending on how different your second mesh is from your main mesh. It might deform very differently.

[@220damien]

Is it possible to Rig a character without a skeleton using this tool to the UE4 mannequin rig?

[@RakizFarooq]

Yes .. a static mesh can be rigged with this process. You can add your own basic initial skeleton and weight paint. In object mode Shift + A -> Armature -> Uefy Script -> Reference Skeleton -> Basic Posing Skeleton to get a prebuilt initial skeleton into the scene. Once you position it in your mesh and weight paint it, the rest is just the same as shown in this video.

The addon is not a "retarget script". Additionally compatibility with the UE mannequin requires a 6 bone spine ( 4 torso, 1 neck, 1 head). These are all parented one to the other. Any extra bone must be on top of them and not in the chain itself. For example a second neck bone can be added to the first neck bone as long as the head is attached directly to the first neck bone too. The second neck bone can not be in the middle of the chain. Similarly you can add additional hip or chest bones or anything else you like. As you can see in the other video. kzbin.info/www/bejne/rGm4l4tsZ7iff5I

This tutorial is not just for mixamo it will work for all characters that have a primary chain of bones similar to the mannequin.

Hello! I bought some characters that are already rigged, but aren’t rigged to ue4 skeleton. I want to convert them over. I have no clue what software the models and rigs were originally made in. Would Uefy work for me to rig them to ue4 skeleton or is it situational? Like, if they were made in 3dsmax or maya instead of blender does that mean they don’t qualify for me to use this tutorial and switch their rig?

[@RakizFarooq]

That is pretty much the scenario I use Uefy 2.0 for most often. The addon doesn't care what software was used to create the characters. You just need to be able to import them into Blender. The only complications that might occur is that you need a 6 bone spine (4 spine + neck + head) and if your character has a different number of bones you might need to adjust some weight paint. The other thing is that you have to delete any morph targets or shape keys while rigging the character and copy them back after you are done. This can be done in blender but is a little complicated and might need additional scripts.

Not sure what you are asking. If you are asking about a different rest pose like a t-pose for the character then yes. You can simply skip clicking on 'Pose Character' during the rigging process and keep whatever pose you want. The downside is that during retargeting in unreal you will need to approximate your character's rest pose in the unreal retarget manager.

Will this work with Daz characters? The Daz skeleton is similar to the Epic skeleton but has more bones in its arms and also has face bones.

[@RakizFarooq]

I don't have any reallusion products but here are some points that might help. In this character's original skeleton there are no twist bones in the arms. But the final rig created with this process has twist bones as they exist in the Epic Skeleton. I can modify the weight paint to make those extra bones functional. Similiarly the Epic Skeleton has only 1 neck bone but the character in this video ( kzbin.info/www/bejne/aKm5d2yHe9pgeNk ) had 2 neck bones. So I deleted one and adjusted the weight paint so it matches the correct final rig. In the same way you can adjust for Daz characters or really any character from anywhere. The face rig might also be rigged with the supported rigify samples. But it depends on how complex it is. For very advanced face rigs it would be better to delete the original and repaint for face rig provided by rigify. Lastly Daz characters may have shapekeys on them. Blender doesn't allow applying modifiers to meshes with shapekeys. You will need to delete them and re-add them after rigging the character. This can be done but it is not a straightforward process. In short you can rig Daz characters with Uefy. But simply clicking buttons won't cut it, some customization is required for advanced characters. You need to be familiar with rigging and know what you are doing. But it can be done.
