heyas; there's actually quite a few channels that p5 adds to things. p4 doesn't choke on them, however, so you can mostly ignore them. (things like the dial groups, the backface culling the smoothing, etc.) p5 reads p4 materials and translates them into p5 shader tree materials... i also think it tries to translate the shader into the 'old' p4 materials (at least it did in sr 1 and previous), when you adjust them. at any rate, they are in there for backwards compatibility, just unused in p5. if you tried to load the figure in p4, was it in the p4 runtime? p4 can't find it unless it is. or there could have been some other type of geometry translation problem when you opened it in p4. the materials would not have caused the figure to not appear. things that make the figure listed but not appear: corrupted geometry rsr (this is usually accompanied by a 'cant find blahblah.obj error'), having too much memory without that memory patch (see the cl web site), or running out of memory in a long poser session. wish somebody would make a p4 from p5 cr2 stripper. ::hint hint!:: you know, like that old pz3 to cr2 thing. that would be nice. :)
