When I use final gather, my settings are... Anti-aliasing min,max 1,3 Filter: triangle Contrast threshold 0.100 Settings for Raytracing... Reflect 2 Refract 2 Max Trace depth 4 Shadow Trace Depth 2 Scan Line-On Faces-Both Final Gather Rays 761 Min, Max radius 24, 240 Hope this helps out. By the way, how are you getting the lego effect. Is it modeled, or is it a bump map?
