I am attempting to create a rig for a car. The rotation of the joints between Blender and Unreal appear to be different, specifically on the root joint. I recorded a video of the entire process, but here is an outline of my steps.
Create armature. I did not rotate or transform it at all. I duplicated the root bone and snapped to where my wheels will be. Nothing was rotated. I parented the wheel bones to the root and named them. I parented my mesh to the armature and assigned the different areas to the bones I wanted.
Export/Import
Looking at the genereated skeleton, the root bone has a 90 degree rotation in X. Somehow, the wheel bones are perfectly normal.
Where did I go wrong? How do I get all my joints to be nicely zeroed out?
