Sorry if this was covered somewhere, I tried looking but didn’t see anything. I basically wanted to create a mechanical chain for a work project, but I didn’t want to do it all physics based. I essentially followed a tutorial on making tank treads and applied a similar approach with an Array and Curve modifier. Once I got the chain looking nice I applied the array and added some things to the chain that would travel with it. Moved the curve, everything rotated nicely.
However, once I moved the whole assembly a certain distance I realized that the chain would slowly expand over time and not stick to the curve’s path. I noticed that the dimensions of the chain were changing with the movement and tried to keyframe those force them to remain the same, but that just broke everything.
Any advice on how to fix this so that the chain stays on the curve?
