How to Create a More Flexible Auto-Spin Expression in Maya

February 1, 2020

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?

That is the topic of Mateusz Matejczyk’s latest tutorial – how to create a more flexible auto-rotate expression. Mateusz shows how you can create an expression that works as expected when you key the speed of the spin.
