I’ve built a few mesh to spline tools based on a lot from this forum. My new challenge that I’m having issues with is aligning meshes that can be indexed, singled out and changed by a variable. For intance: If I have a spline with 5 cubes attached, I want to single out the third cube and change the color properties or add a decal or make transparent only to cube number 3. Any thoughts on how to add this functionality?
