Hi, I've run into a classic vehicle rigging problem - automatic wheel rotation based on direction and distance travelled. Without using a path constraint, what's the best approach to this problem within APEX?
Excluding path constraints, the consensus in other DCCs, and Maya more specifically, is:

1. The expression editor. The expression editor runs on every frame or when an input to the expression changes. In this case, you can get your solution from the previous and current frames.

2. MEL

I don't use Maya so I can't speak on the pros and cons of using those methods, but they appear to have effective solutions to this problem, and I would like to know if there are any possible solutions within APEX. I've attached a video that shows the issue in Houdini along with a file.
