Hi

Trying to blend 2 meshes of the same character imported in FBX format.

One is in static T-Pose. The other is animated.

I assume you need to use a Blend Shapes SOP but have had zero luck getting it to work. Any rigging experts possibly able to set up a bare bones(pun intended) .hip showing how to accomplish this?

Can you explain a bit more what you are trying to do? Simply blending between the T pose and the animated pose will result in the geo moving linearly to the target position… not at all natural and all sorts of intersections will result.

with fbx you can also save all the keyframes as a clip also t-pose as a clip, blend in CHOPs using Blend CHOP or Layer CHOP and export back onto your rig, that will result in less linearly looking blend, however intersections may always occur
