i have a experience im making and i have a baked animation in blender(no bones) and i can leave the scene and come back and the pivot of rotation on my object is either perfect or randomly off.

at first i thought it was when i was behind objects and the culling was making it lose its pivot but i havent been able to recreate it everytime.
