Is there a recommended way for converting an arbitrary posed mesh to a t-posed mesh?

Side Question - Also since you are able to calculate skinning weights of a mesh, why isn't it possible to do neural blend shapes on any arbitrary posed mesh?

Hi, as far as I know, this is still an open problem.

First is we are only able to calculate skinning weights for a T-posed mesh. Second is that neural blend shapes for now is only learnt to compensate deformation artifacts starting from T-pose: it requires different neural blend shapes for non T-pose.
