Thromm arcadia, well i don't have the time for rendering things with raytracing. Actually, i've rendered with raytracing in P6. and yeah, you get exceptional shadows and shading, but besides that it looks just the same as with my IBL light setup( ibl + one spot light) and render with no ray tracing. Really. i've test rendered several pics with ray tracing on.. took like 8 minutes to render one big pic. it was super nice, but what i do now with NO ray tracing is great and it takes lik1 minute. that's way better for me.
