I posted an animated solution to one of my 3d printed puzzles. It is very simple using only translation of the 6 pieces done in Blender. However, the pieces are offset so it doesn't go together correctly. I rendered an AVI of the same animation in Blender and it is correct, but not in the FBX export as displayed here. What could be the issue?
