regarding that tiara model, is there something wrong with my monitor, or are those diamonds flat, and the hexagonal mounts disconnected from each other? p.s. I tried doing caustics with a diamond in poser, but gave up after an overnite render that looked like a piece of window-glass. took about five minutes to render in carrara. after 50 minutes in maxwell render, I got a grainy image that showed promise, but I later learnt that caustics and especially dispersion (fire) slow maxwell down to the point of unusability.
