I try to make a conveyor belt, but I have a problem.
How i can do many elements move a circle continuously?
Is there better option than creating additional points?
You absolutely need a point for every change in direction. The more straight sections you have the better. You could Lerp in between the straight points.
The problem is now going to be the amount to lerp each frame. It must be proportioned to the length of the segment. If you do not, your spacing is going to change. This “cure” would definitely make your
beforeRender code more complicated.
Vector3's are pretty cheap.
