I have a couple of animated and rigged characters that were given to me to make an instagram filter using Spark AR. They look fine in Cinema 4D but the problem is that when I export them to Spark AR in .fbx, they are horribly deformed. I've tried cleaning up the rigs (they had nulls inside them), baking the animations in, auto-weighting the rigs and nothing works. Does anyone have any idea of what might be wrong?
