Probably a lot I don't know about it, but specifically, why the difference in intensity? The 2 pics show the same scene (a .pz3) rendered in P4/P5. Nothing touched. P5 options were - production/cast shadows. I also tried draft (really horrible) and raytracing. All lights are spotlights, and the settings in both apps are identical. Shadows are depth-mapped in P5. Now, I just spent 2 full days creating light sets, and I'm trying, really trying, to make all my stuff P5-compliant, but poser doesn't make my job any easier. It keep reserving suprises for me. The materials are all fine, I double-checked everything there. And yet, one room looks as though it came out of a speilberg movie. So, I'm baffled. Any thoughts? mac
