Because Spaghetti create splines with a lot of verts it requires the most optimization, but its still faster then aligning a spline line by hand over a complex shape. To optimize it I set the weld threshold kind of high 10-20 and it gets rid of a lot of the jag and weirdness but not all of the vert/spline weirdness goes…
I like to use the Advanced Painter script for 3dsmax, it's toothpaste and spaghetti mode allow you to make wires really quickly because you to paint your wires where you like on any given piece of geometry. They are kind of poly intensive but can be optimized fairly quickly because it uses splines. I normally bake them…
