Mateusz Matejczyk shows how to create an auto-spin expression in Maya that works better when you change attributes over time.
Likely one of the first expressions people learn in Maya is to create an auto-spin. It’s a simple one too, where you multiply a frame value by a speed attribute such as rotateY = frame * speed. The problem we run into is that if we want to key a change to the rate of the auto-rotate attribute, it doesn’t work as expected.
Need to Key the Speed?
