Yes I am asking for help again on “twisted mesh” on re-targeted rig.
The source rig is a BVH file (created from VRM tool) and re-targeted rig (imported with MMD addon to Blender). I am using Blender 2.92.
Attached is my final results file.
I had “aligned retarget rig bones” same as the source rig bones" using retarget tool (keemap)
The animation transfer from source to retarget rigs works fine.
However b’cos I align retarget rig to source rig, the retarget rig that has a mesh … both its legs mesh get twisted.
I have attempted the following but failed.
- In pose mode, try to correct bones rotation to ensure the mesh is ok … but this will result in the animation transfer get distorted.
- In edit mode, try to correct the bones rotation … but this does not work at all.
The problem is X, Z is about 45 degree difference between the source rig (BVH) that has the animation, and the re-target rig (MMD rig). I tried using Mixamo rig … same problem; that is able to transfer the animation nicely after align the bones, but the legs mesh also get twisted.
So question is, how do you ensure the mesh don’t get twisted?
Or is that is some not possible … that source to retarget rigs only works with bones? and not the mesh in Blender? or in general in any other tool?
Hope someone can advise so I know if I should give up the idea of “retargeting” to a rig with mesh that differs in bone alignment with the source rig.
