Thank you so much for this detailed and very useful tutorial that doesn't make me hide my browser when people walk past.

[@Userjdk11031sks]

Thank you for your good information. It was very helpful for the work!!😀😃😄

[@tbowren]

Kamila, great starting tutorial,. I'm excited to watch the rest. I really liked that you showed 2 ways to attach extra skeletons to a main one. This is very useful in modular character creation, even without using physics. Thanks for making this.

[@kamilabianchi]

Thank you!! 😊Your elephant video that actually inspired me to look at this topic again.

Thank you! This tutorial is both informative, useful and clear! Just what I needed, and way more classy than most others! 😅

[@mikemelnik9155]

Finaly I've found the video with proper explanation! Thanks a lot!

[@glitch_city_gamer2846]

Thank you so much for sharing your wisdom in a family friendly way on a topic that is so key to creating natural looking animations across a range of art styles. Especially considering you're such a heavy hitter in the industry, you've worked on some incredible projects. It seems really difficult to see "behind the scenes" and how it's really done at top gaming/animation studios around the world.

[@gameof.football]

Took KZbin ages to finally offer me your videos. This video is great and looking foward to jiggle physics without looking at female parts (there are other places on internet for that 😂😂😂). Just and idea if i may, juggle physics on animal like horse or any other with short fur or dino would he great. Even if animal looks like a chair with 4 legs 😂😅😊 thank you for your hard work and sharing your knowledge

[@kamilabianchi]

haha exactly! You mean the actual 'fur' simulation? Like hair? Or just as a skeletal mesh as well?

[@gameof.football]

@@kamilabianchi fur with skeletal mesh would be great too. But I was thinking the jingle of the muscles with a bit of fat on animals. I think dinosaur could be good for it because it is usually without fur.

[@kamilabianchi]

​@@gameof.football For that what I've done before is using cloth to simulate some muscle movement. You paint it with a minimal influence, so it's very subtle to see. But I made a note about a video on this.

[@erickendoka2953]

Thank you very much I deeply appreciate your videos 🙏🙏🙏

[@cj5787]

I think you can call some function in the animBP so it can collide with external physic asset

[@jochimera3008]

Thank you for making this tutorial, happy to see a non-boobs focused one!

[@cowsmanaut]

great tutorial, nice to see something new and I learned something new with the second way you attached the hair, didn't know I could do that thanks!. Should not the hair physics component already collide with the character physics components by default? Then you should have collision with the arms for free if the character has theirs set up correctly.. This is how it works with hair systems, cloth, physics constraints etc in Unreal. I would be surprised to find it doesn't work if they are in the same blueprint. Setting up physics constraints for earings on a previous character ended with me needing to adjust collision on my character.. I'll need to test this out later..

[@BeastFistsGame]

Thank you very much, great tutorial

[@davav2688]

Great tutorial, thanks

[@louvlina]

Hello, I know that not many people will need this advice because no one is as clueless as I am, but if at any point in this tutorial the rigged part of your mesh disappears while the bones remain, I think it’s because you didn’t export your character from Blender to UE5 correctly: in Blender, you need to set the units to metric and change below the scale to 0.01. Then you should scale your armature and mesh by 100, and finally, you’ll be able to export your asset to Unreal Engine and follow the tutorial properly. Hope this will help at least someone bc I struggled with this like a lot of time lol

[@ismaelnavales5492]

Great Kamila!! Thanks a lot for sharing it really Worth

Thank you so much, it was really helpful! I'm using this on morphed metahumans, but I was thinking there should be another way for a ponytail not to clip with the body. I've searched everywhere online but I can't seem to find the right collision settings for either the ponytail or the body... would you have any idea?

[@lorenzo_cgi]

Great tutorial Kamila! is possible to merge two physics asset ? for example merge into the physics asset of the hair the physics asset of a body, so basically i use only one physics asset for more accurate collision, instead of a big sphere. Thank you

[@kamilabianchi]

As far as I know, no. :(

[@mdp7193]

Thank you for taking the time to make this tutorial! I need help with one thing though, I followed everything and for the most part is works very well, but my hair is all stretched out and very jittery... I've been researching but having a hard time finding what's wrong... anyone knows a fix for this?

[@kamilabianchi]

About jittering, try increasing the damp value and see if that helps. Unfortunately Physics assets are a lot of trial and error when testing numbers.

[@sunny99179]

Lol i surrended about backpacks because i did not knew how to make it follow my char and how i would riggate to it bounces on back while walk. I also got frustated rigging on blender, trying on character creator and no help... so i maded a simple biped rig on blender.. i had no sucess on ik in unreal to legs, if you have any tutorial i will be happy to follow it, the official did not worked.. Ok let me ask you something: after see this 1st part video i want to know if i can make a character full like hair joined and cloths, import to unreal and make coliders and all the physics you teach here on the "body" and body i mean the character with hair and cloths joined.. so i could add bones and more colliders to make it work on a single "mesh", is it possible?? Thank you So Thank you very much!

[@kenalpha3]

"could add bones and more colliders to make it work on a single "mesh", is it possible??" Yes. That is easier. What she showed is for modular characters (characters made from different "cutouts" of meshes > to merge into one, like the hair merged onto body). But if you import hair + body as one mesh, then it is easier to setup physics in UE. In Blender, just add bones in a line for each hair segment (like a snake). Search YT for tutorials on how to Weight paint/add hair bones.

[@ajibolalaleye769]

Hi thanks for this. I'm having a little issue. I have a setup similar to yours but the center ball is knee so it gets animated with the character. And when I. The running animation. The knee seems to just pop into the clothes physics bodies in front of it. Other times it works fine with the physics any advice will b great. Thanks

[@kamilabianchi]

Hey, unfortunatelly the only way is by adjusting the size of the capsules in a way they won't collide as much. Also make sure to tweak the constraints, so it's not moving so 'freely'.

[@BadPractices]

Great video but I have one question. I have a skeletal mesh with both braids, and a few extra dangling bits of hair. I have followed the steps exactly, but for some reason my hair and my braids all collapse into the center of the hair. Do you know what could be causing this?

[@kamilabianchi]

Hm, it's hard to tell without seeing it. But it could possibly be that they are colliding with something else. Does the body have a physics asset sphere as well? When you open the physics asset, and press simulate, does it collide straight away, or does it happen only when you are in the play mode? Try to narrow down where the issue is coming from first, and go from there.

[@BadPractices]

@@kamilabianchi I’m simulating it without the body at the moment just to have one less variable to worry about and the problem persists. The hair braids and strands all immediately collapse into the direct center of the hair like a vacuum. I’m wondering if this is caused by my hair mesh being a bunch of separate meshes joined together in blender rather than being one singular mesh. (I joined them to have an easier time UVing them rather that connecting them with a Boolean)

[@kamilabianchi]

Yes, sorry. Hard to tell what's causing it...

[@JonCG]

and by the way Kamila,you could add aswell on how play is on Sequencer on this approach it doesnt work me.thanks in advance,Great tutorial

[@kamilabianchi]

For that to work in sequencer you need to "play" the game, the button that you can hit "simulation", you know? That way it would work in Sequencer and you can render from there. For rendering you would have to add warm up frames to it calculates before animation starts.

[@JonCG]

@@kamilabianchi Thanks, Yes i know that,on cloth.that's what i do.but when it comes to hair Pysics simulation it doesnt work for me

[@kamilabianchi]

Hm, I am not sure now. When I have some time I will check this again.

[@AndJobs]

Já inscrito. Excelente tutorial.

[@hyper_1337]

Is there any way to do this but the simulated body can hit other meshes in the world?

[@Tanjiro2424]

Hi Kamila! Would this same method apply to cloth physics? I am trying to create a game character where the dress has physics, but I've heard the best way is to use bones as cloth sim is really prone to errors and bugging out during gameplay

[@kamilabianchi]

Hey, I have another video on cloth: kzbin.info/www/bejne/mKvKaoWopaeKgdk&ab_channel=KamilaBianchi But yes, cloth sim is definetly not the most reliable one, it's hard to debug when it's not working, etc. So with bones you can have more control over the movements, although, it might not look as nice/ realistic, especially if it's a thing / light cloth.

[@Tanjiro2424]

@@kamilabianchi Thanks a lot! I’ll check this out

[@Pixelboyable]

Can yoy explain the difference if when to use rhe ik rig vs the control rig? The unreal documentation doesn't really make that clear.

[@kamilabianchi]

Control Rig is mainly for animating in Unreal, like you would do in Maya/ Blender. IK Rig is a system to edit / transfer existent animations. docs.unrealengine.com/5.0/en-US/unreal-engine-ik-rig/ You can use both systems in a game setup, to adjust systems automatically like foot placement, etc. What I found in Unreal is that there is never only one way of doing something, and if it works, you stick with that solution. :)

[@oberdoofus]

thank you for this! Super informative! BTW Which program did you use to rig your hair? I'm trying to find out more about rigging hair (in bender) and in particular the structure / heirarchy bones. I notice in yours you include the whole body - with spine/clavicle etc? Also a crate? Have a missed a previous tutorial?

[@kamilabianchi]

Hi, I explained in the beginning that I reused a character from the Cropout Project in Unreal. The only thing I did was adding extra spheres to the hair so it was longer, and you could do that in Blender.

[@KittehBit]

Would it be possible to also make the torso (on the other skeletal mesh) a physics asset and use its collision for the hair? Estimating the shape of the body seems like too much of a guess work and it doesn't take the arm movement into account. Good video. :)

[@kamilabianchi]

What I would do is copying the whole skeleton to the hair, so you could add the collision to the "arms" as well. But as far as I know it wouldn't work if they are different meshes. I might be wrong though

[@DRockafella]

I've been stuck for like a week trying to figure out how you got to what you did at 2:30 . I even did your Unreal IK Rig tutorial, but I am still clueless. Did you edit the hair mesh in unreal?

[@kamilabianchi]

I edited outside Unreal, you could use Maya or Blender for that. Created more 'spheres' for the hair and extra joints, and skinned them. Is that what you are asking about?

[@DRockafella]

@@kamilabianchi Ah, thank you. I was trying to figure out how to edit the hair and add extra joint inside of Unreal, but I guess that is not possible.

[@kamilabianchi]

@@DRockafella Yes, sorry. There is a way of doing it using the new skinning tool, but it can get a bit complicated: kzbin.info/www/bejne/qmiogmh3qb17jbs&ab_channel=KamilaBianchi

[@DRockafella]

@@kamilabianchi Thank you again! I will do this tutorial too. I've managed to get the hair into blender and add a few blobs for the hair. Now I have a quick question about the new bones in the hair, is that done in Blender or Unreal?

[@katandmark]

@@DRockafella We converted the SKM to a static mesh within Unreal and used the new modelling tools. Tri select (Mesh), then flood fill (Selection Edits), create poly group (model, Mesh Edits), which you can then select and duplicate (also under Mesh Edits). Then simply convert the S back to a SKM using the exisiting SKM you can then add the bones in from there which is pretty straight forward. The UI is still a bit buggy though as the feature is still in beta. Thanks to @KamilaBianchi for this series!

I try to add glasses to my body but when I use "set leader pose component", my glasses disappear ! Do you have something special on the bones of your hair ? Like same names of bones ? I figure out that my glasses are too small, minuscules ! And with a bad orientation.

[@kamilabianchi]

The hair has the same bone structure as the body, and added joints are all scaled as 1, and with correct orientations. It looks like there is a problem in your glasses skinning / skeleton.

[@JDARRASVP]

@@kamilabianchi The answer [Blender to Unreal Engine 5] Correct FBX Export Settings for Characters ?

[@kenalpha3]

First, are your glasses a Static Mesh (no bones) or Skeletal Mesh (bone joints for the glasses, like a jaw bone pointing forward, and you would want it to pivot up/down)? Or perhaps in Blender, add glasses mesh at the face (if your character will always wear the same glasses). Then rotate the glasses mesh a little, make a copy of the mesh. Merge it to make a Morph Target/Shape key. Which means the movement will go from 0 to 1 (all the way up or down, all the way right or left). Then in UE, you control this 0 to 1 that changes the mesh angle slightly. And to get wiggle, use a random # when Character is moving.

[@JDARRASVP]
