I want to use the change in rotation between the current and previous frames to rotate another object.
EG object A was at 30 degrees in Z axis last frame,
and is now at 35 degrees in Z axis on the current frame,
so has changed by +5 degrees,
so i would want object B to rotate by +5 degrees.
How can i get Z rotation value from the previous frame, and use it in a driver?
I have practically no python knowledge but from other similar questions this might be the only way, but i don't understand how to actually make a script work with my driver.
