Not sure if this is the right subforum, but here’s my question:
My scene includes a piston, with a setup resembling this:
The red and blue objects can reposition freely along the X and Y axis, and when they do, I want the yellow and green sides of the piston (which are children of red and blue, respectively) to automatically rotate so that they face each other. Thus, the piston will contract and expand as red & blue move closer and further away. What’s the simplest way to do this?
Thanks!
