I'm still using both P4 and P5, at least until the Walk Designer is fixed.

I haven't added anything to my gallery in months, but I've posted images here in the forums.

This was a comparison of P5's displacement mapping to P4's bump mapping.

Most of these were rendered in Poser 5 (mine, anyway; MaPPer's are P5, also, I believe). Note the first image; no crosstalk between figures. The stream images demonstrate raytraced reflections.

More P5 renders; no crosstalk. The grassy field was achieved with displacement.

This thread demonstrates some of P5's animated-material features.
