Sorry...forum software ONCE AGAIN has decided not to email me about replies to a thread. Which just one of the reasons I'm at DeviantArt these days and only check in here once in a blue moon. Anyhow. Really lovely, Shonner. I love the way that rounded box looks. UVDan, I'm not sure I could even find the shader around any more. I remember more-or-less how it was done, tho. Something like two recursions of the bricks shader; one was set for the narrow channels, but the other was set for really wide "grout." The grout is specifically the spacing of two rows of rivets...which were in turn a checkerboard filled with gradients with cut-offs to make them small mounds right in the center.
