Okay, tell me something. I want great renderings in a fairly quick amount of time. I'm patient but I do have my limits. I've been experimenting with all the above (FG/GI/Caustics) with the Mental Ray renderer with no area lights and we'll see how bad it looks. Can anyone here set me straight with advice or tips or help on how to use Caustics or GI in Mental Ray? FG seems to just slog my computer down to a deathly crawl. THANKS!!!
