Actually, I didn't notice the bricks until you mentioned it. Have you tried only resizing one direction? Scrunching up the <--> direction so it makes them more the shape of regular bricks? (Altho', I'm sure I've seen some shaped like this, if not in these colors.) Is the tile a separate material? If so, you should be able to adjust the components of it to get rid of the reflections. If it's not, maybe make it one? It's hard to tell if your tile is a single item with a mat or if you've booleaned it to get the grooves. If it's booleaned, a flat layer just below the surface to mimic the grout would work I'd think. 'Course that's the hard way 'round it. Hey, how about some faint caustics on the ceiling and walls? That would look cool! All in all? Day-ummm! This is wonderful! :o)
