I have and the good news is, there's a fix! 1. In MotionBuilder, open the "*_FaceMesh.FBX" file you have exported from Unreal. 2. Open the "Skins" window from the "Window" menu at the top of the screen. 3. Select the *_FaceMesh mesh object in your scene - be careful there are sometimes 2 objects with this name: the root object of the character hierarchy and the actual mesh object (the mesh usually gets renamed to "_FaceMesh 1") 4. Alt+Left-Click-Drag the mesh into the "Model List" in the "Skins" window. 5. Close the "Skins" window. Presto! It should be fixed - adding the mesh object to the Skins window seems to reset the Skin Cluster type and fixes the skinning issue. Hope this helps.

​@@mocappys God thank you so much! It worked. I wasted so much time looking for a solution. Best alternative solution was export FBX from UE5 -> Import it in Blender and from there export it again and import it to MoBu. But you gave a legit solution!:) Thank you and looking forward for any new material from you!

did you ever found the solution, I'm having the same issue with all the metahumans that I've tried and can't figure out why is this happening.

How much do you think is a good price for those courses? What would you pay? - genuinely interested, not angry:)

Many congratulation on the new role! Makes me so happy to hear these videos gave you some practical experience before you get into the crazy that is production. Good luck!

​@@mocappysHello, i have doubt Whats the difference between aux pivot and auc affector and which we use when. To me as a newbie both looks same to me. If you don't mind can you explain a bit to me. Thanks

Characters are from a character creator (pre-metahuman) World is built in Maya. Lighting is done in MotionBuilder.

Are you using Maya keyboard shortcuts in MoBu? If so, you’ll need x-drag instead of alt-drag.

@@mocappys Oh yes, thanks a lot

Yes, this was all done in MoBu 2020 which was Python 2.7. Print statements do need to be in parenthesis. If I get chance, I update the script on my site for Python3

Hello, it’s hard to say without h seeing your code, but it looks like the object you are passing as “xmlFilePath” isn’t a file path to an xml file.

Hi, yes, a lot of big studios still use MotionBuilder for editing mocap for games.

oh I had found out my template.xml lack a prefix, it cause 'charHipsObj' become 'No type'.

Thank you! That makes me happy. It’s the reason I make the tutorials. Good luck with the anim test🤞

You are very welcome. Thanks for the kind comments;)

Okay I may have found the issue, I reverted the retargeting type scaling to Animation and not Animation Scaled, and that has corrected it somehow? Not sure if this is correct or not but seems to be

Sounds like you’re using Maya keys, in which case you need to use x-drag instead of alt-drag

Thanks! Appreciate that. More to come from the Matrix scene. Got to run up the wall next!

Hey! Thanks, Marco. Hope you're well :)

Yes, here's the script I use to characterize the MetaHuman. kzbin.info/www/bejne/qp3blZKwmryAjqM mocappys.com/how-to-t-pose-and-characterize-your-character-using-motionbuilder-python All you need to do is swap out the HIK.xml in the script with the name of your MetaHuman character definition XML. This is the line in the script charSkelDefDict = convert_skeleton_definition_xml_to_dict("HIK.xml")

@@mocappys I tried to do that but i can't get past an error with line 31. It's complaining about expecting code to be indented. Would it be possible to upload the script as a whole? I know it sounds lazy, but it would save me (and I guess many more) a headache. In any case, thanks for the awesome tutorials!

It sounds like the formatting isn't copying correctly from my site into your python editor. I'll see if I can find a better way to display the code that doesn't break the formatting, AND I'll combine it into a single script at the bottom of the page as you were so nice about my tutorials :)

@@mocappys Thanks for the extra effort! Looking forward to it!

Yes, there’s this tutorial👇 that’s shows how to do all that… kzbin.info/www/bejne/Zpu9oHasnNN_bMk

You are very welcome!

I'll appreciate the "oh so good". But why scary?

The coding part still scares me 😅@@mocappys

Sorry, about that. I forget to say what shortcuts I'm using sometimes. The next video has the keyboard shortcuts on screen when I don't say them. Hopefully this makes things easier :) kzbin.info/www/bejne/bYPFZ3WOYsuAe8U

The name tool uses string matching, so you can type in the exact name of an object you are looking for, or you can use wildcards for partial matching. For Example "*_joint_*" to find all the objects with "joint" in their names. Here's the script I used to characterize the MetaHuman: kzbin.info/www/bejne/qp3blZKwmryAjqM mocappys.com/how-to-t-pose-and-characterize-your-character-using-motionbuilder-python All you need to do is swap out the HIK.xml in the script with the name of your MetaHuman character definition XML. This is the line in the script charSkelDefDict = convert_skeleton_definition_xml_to_dict("HIK.xml")

You're welcome!

Ok, I found it out eventually :D just select the bone in the character control interface, double-click in the bone name field, delete the name and click ok.

Saving mapping definition! Thanks God for that!

Couple of options for you: The inspiration for this video: kzbin.info/www/bejne/ap6ymoqPqbisb9k My MotionBuilder Course: academy.mocappys.com/p/how-to-animate-character-with-mocap An alternative manual approach: kzbin.info/www/bejne/oqOZga2fhL5rbrc

@@mocappys gentleman as always thank you.

Totally agree. I try to get a “best fit” with the retarget settings and fix the rest with layers - more of an animation approach. But you’re right, there are some powerful things you can do with the retarget settings during the remap. A lot of the fixes here were adding data that wasn’t captured by the mocap systems.

@@mocappys I find taming down the head with a slight reach on translation and rotation to be necessary to avoid the bobble head + the godawful bent knees on locomotion or Smart Objects in a lot of games out there. Anyhow, thank you again so much for the tutorial 😀

Thanks, Aline. Great advice! I’m with you on those bent knees

Hi, The script on my website should let you characterize any character as long as you have a Character Definition XML file for it. All you need to do is swap out the HIK.xml with the name of your MetaHuman character definition XML. charSkelDefDict = convert_skeleton_definition_xml_to_dict("HIK.xml") Hope this helps

@@mocappys Hello, thanks for the tutorial! Any chance you could share the metahuman character definition XML you used in the video? Can't find one online and it would save a ton of time to have it.

Hi, For single character animations like the dance I use in the video, it shouldn't make a difference because the rigs are globally scaled so all the limb lengths and pivot points are the same. It would make a difference if your character interacts with something, like a second character, environment or prop object. In these situations, the distance your character moves, stride length, reach, etc, would be different so the alignment wouldn't work, if that makes sense. Ideally it's best to work with the correct scale character whenever possible, but if you can't or haven't, the animation would still work in some situations.

@@mocappys ok got it, that makes a lot of sense. Thank you!

It depends what you are doing and what format the animation data is in. - If it’s skeleton or marker data you are using to remap, you can change the orientation of the root of the skeleton or marker data to something like -90, 0, 0 (xyz). Then when you remap the data to your character - If you are importing animation onto your character, you can change the rotation on the Reference node (usually the parent of the character hip joint) either in the scene or Character Controls You might have to rotate the character back to its original position when you export, depending on how you plan to use the final data.

Thank you. I hadn't seen your tutorial, but I will go and check them out. I actually used this tutorial from Pixel Prof Metahuman into MotionBuilder - kzbin.info/www/bejne/ZnXCZ4Gvqp6Xga8

@@mocappys I mean the fingertip management part

Oh, this isn't the first rig I've worked with that didn't have finger tips :)

@@mocappys sorry I didn't get it, my English isn't so great 🥴

Happy to help round it out

Thank you. Beast is what I aim for :) Sorry about website not working for you. What error are you getting? Does this link work? academy.mocappys.com/p/how-to-animate-character-with-mocap

@@mocappys "Beast is what I aim for :)" Your mind works different. I can say it even by your replies. )) Nice. So yeah thanx! I am in. Is there any interaction included in that course? Like answwering some questions and such.

@@FxmediagroupRu If you have questions about something covered in the video lessons, you can post them in the comments section in the lessons and I will answer them. Is that what you mean?

@@mocappys yes thanx. Its great. I found discussions in the example lesson.

I'm the same when I watch one of @riggingdojo videos. To answer your question, I left the fingers in the standard MetaHuman relaxed pose because I didn't end up retargeting the data from the gloves/fingers of the actor skeleton. I did this because it's so much easier to look at the relaxed hand compared to paddle hands. I do the same whenever there's no finger data If I was going to retarget, then I would do the same as you and straighten the fingers and thumbs - I actually did that at first, but then changed when I saw the finger data.

@@mocappys (Dave again, replying from my business account) I'd not heard of riggingdojo, will check their channel out for sure. Thank you for the explanation of the hands situation - that makes total sense. If you have a moment, I'd love to hear any comments you might have on my project - I've been working on a Daz to UE exporter for the last year or so and am currently beta testing with around 100 users...

Hi. Here's a link to the script to t-pose and characterize a character: mocappys.com/how-to-t-pose-and-characterize-your-character-using-motionbuilder-python/ You just need to change the "HIK.xml" for a "metahuman.xml" character template, once you've made it.

@@mocappys Thank you very much Simon, much appreciated!

13:10 Stangely mine came with tips but misplaced... 🤔

Glad I could help. Interesting! Maybe it was the version of rig you used to build your metahuman?

@@mocappys It was late here when I tested that, the tips came from the characterization that I did too early, now with fresh eyes, I believe I just missed the hiding part (probably in your script?), from memory: - * _ half _ * - * _ mcp _ * - * _ side _ * - * _ in _ * (minus the spaces, YT formatting drives me crazy, it doesn't support escaping 😅) Thanks again for this, sooo useful, there are tons of videos on MH but 90% are just very high level, or doing things actually wrong.

@@workflowinmind my script (in the video) actually adds the finger tips to the MetaHuman, just to confuse things even more... don't forget * _ out _ * for your list - I see what you mean about the formatting;) Thank you. You're too kind.

@@mocappys Perfect thanks! Oh yes and last thing, you can import metahuman blenshapes fine in MB, I use it for facial mocap editing (you don't get the secondary rigging goodies in the viewport but they import back fine in UE)

Gotta be done, especially when one will cause MotionBuilder to crash;)

Yes cheers Simon!
