To explain the problem a bit better, here is a capture :
On the left a metahuman based on the female medium normal weight which is the default character. I apply mocap on it, and bake it to control rig, everything works fine.
On the right, a metahuman based on male tall underweight. If I apply the same mocap, it works fine. Then I bake to control rig, and it does scale the whole model up (red circle on picture). It looks like it applies the difference between the default template and the male tall template AGAIN when baking.
Any help would be really appreciated as I can’t find a way to clean my mocap with this bug.
