I have a mesh that was delivered to me in A-pose, and I would like to be able to retarget mixamo and other animations over the course of the project. The problem is I can't figure out how to get the mesh to adopt the new pose structure.
Mixamo animations rest pose is a T-pose. I can skin the model by deleting the animation setting it into an A-pose. Applying the animation again without resetting the armature to an T-pose results in the arms being crossed (the result of adjusting the upper arm rotation). Trying to skin then reset the armatures rest pose to a T-pose results in the mesh not retaining its position on the armature...it reverts to an A-pose.
This SURELY must be something people come across all the time.
