So this will be the end result for now. I may go back and add some detail if I think it’s necessary, but I’ve been spending waaay too much time on this, so I should move on. I also created a variation in structure (which is actually a whole new graph, because the original one was not as optimized as it should have been), which will be used for a bit smoother surfaces.
I chose a rounded cube as the render geometry. It serves the material much better.
