Short summary

Convai animation not works on far human proportion

What happened?

I am making a character and the character proportion is so different from human proportion like short legs and long arms and Convai is have their own animation, if i applied the animation its back to the human proportion again

do you guys have solutions for it?

What did you expect?

making metahuman and convai character proportion free, like it works in any proportion

I checked the relevant documentation, resources, and similar forum posts before posting.

where can I find that resave all? is it in the content browser or inside blueprint?

my character proportion is far from normal proportion is there is a way to solve this
I tried to resave all option but it doesnt work I think this is a different problem

Oh, okay, I see the problem.

Which blendshapes are you using?

actually Ive sculpted the character on zbrush and the metahuman topology and the one that i sculpted is same, so i just export it in zbrush and import it in maya to copy and paster the vertex order to able to work in unreal engine. i imported it in unreal engine and Import the body and face inside metahuman builder and i just click the rig in the end

and i just used convai_metahuman body animation and I think its not compatible because of proportion

For emotion and lip sync to work correctly, you need to set up the lip sync configuration for your character.

Please make sure the character’s blendshapes and lip sync mapping are configured properly.

i dont have problem in the face area my problem is on the body so from original short character and I applied the convai animation and it stretch longer

Yes, this can be supported, but the main issue is likely the body proportions and animation retargeting.

Our current Animation Blueprint is built around the MetaHuman animation system. While the body animation logic can be adapted to other characters, the character skeleton needs to be properly retargeted or use a compatible rig. If the character has very different proportions, such as short legs and long arms, applying the default Convai/MetaHuman body animation directly may cause stretching or force the character back toward standard human proportions.

In your case, you may need to create or adjust a custom retargeting setup for the character’s body so the animations preserve the original proportions correctly.

in metahuman character builder it works fine there and he moves perfectly, but I after I assign convai animation it stretches up

is that retargeting still needed? or is there is a way to fix it rather than retargeting

You can try using the Reallusion Animation Blueprint instead.

thank youu
I tried it but I think this one is different, the proportion is so different from human proportion maybe this one cant work?
