I’m going to try it on some Corian, which is pretty consistent. Not sure if I can find settings that will work the way I want, but at least I’ll give it a shot. Leather would be interesting too. It’s pretty tedious adjusting the linear gradients for each of the sections since I wanted it to have an organic look. Theoretically there are only a few tiles to the design and then you flip and mirror them. In practice I was doing some manual adjustment on the gradient nodes and I couldn’t get them to go around curves the way I wanted. That’s where the mesh gradient comes in, but I’m still trying to figure that out.
Here it is with the linear gradient nodes showing. It is a reflected gradient to it goes from black to white and then white to black, but the gradient is always tangential to the axis of the gradient line. Just figuring this out. I really need the gradient to fan out.
This is a radial gradient:
I think it is something like this that I need.
