@queri - ok, I think P5 has serious memory leaks, but the P5 version is seriously different from the P4 version. In both versions, there were sample light sets included. I tried EC1 with P4, it didn't work... and the sample light set, together with V2/3 figures/textures and P5 hair gave the usual result - it gave up in the middle of the render. But with ECII, there are a lot of differences. OK, one can still concoct a mixture that will cause p5 to give up, but I'm surprised at how well the lights render - it caused a smile to break out in an environment where there was often no smile in the last few months (my face). @AprilYSH - dunno how long bryce takes... raytracing? - is an option in P5... was it there in earlier versions? :-))
