I do have the same Problem. It looks like the mesh of the puppet tool is not in the correct space. I built a 3d Comp and a Camera. If i am moving the camera, the puppet mesh stays relativly to the camera but not to the object, where it was casted on in the first place.
Precomping is the last way* i want to go. Rasterisation and also bringing all my keyframes away from my main comp is not optimal.
Is there any solution to this? – thx
*thats what i am doing right now.
