I have an object, a quadcopter propeller. I applied a double mirror to generate 4 propellers. Then, I animated the propeller so it rotates. This produces the four propellers to rotate in their places (this is the desired output).
However, if I apply the mirror modifier or if I export it to an fbx (which I need to do), the animation changes and all the four propellers start to rotate around the original one, which continues to behave in the same way.
Is there anyway to avoid this behavior?
