Wheel rotation = change colour

Hey Folks, I’m new here - and this may be an easy question or a crazy difficult one!

I would like to change the colour of an object based on how fast a wheel is rotating.

I’ve been looking at Dynamic Materials, and am able to change colours based on collision box - but can’t find any info to help me with my question.

Any tips would be most welcome!


Well, I’m guessing in some ways this is like creating a rev counter, finding a given value at a given time, and constantly passing that value onto an animated colour ramp. Just thought this would be worth a bump, in case anyone has any links/solutions/ideas to help me investigate further?

thanks guys…
