Basically, I have multiple .FBX files from a game Asset I bought with one containing the actual mesh of the model and it's rig but no animation and the other .FBXs containing one animation each. The problem is that the Rest Position for each animation is different (despite them all using the same armature and bone names etc.). For example my "base" Armature is in a standing Rest Position and one animation I am trying to import is a couching walk animation. The Rest Position of the .FBX with the animation however is already in a crouching Rest Pose. How do I get this to work?
I have found this question which seems to be about the same problem, but I am not sure how to use the code provided by the answer: Two armature, two rest pose, fixing animations
Any help appreciated.
