The -only- issues you may run into with Kozaburo's hair pieces are: 1)Transparency settings. Vue can be a little more finicky about the transparency settings (straight out of Poser you =may= get a setting that isn't quite transparent, so you have a ghost of the mesh that should be invisible). Simply tweaking the transparency slider in the material window fixes this. And 2)You may come across a situation where it seems that there are polygons missing. This is the result of his modelling; some of the polys are actually backfacing. This didn't matter Pre-P5, but with the backfacing poly removal, you can have trouble. There are some easy fixes that I believe are detailed in the backroom of the Poser forum...or a forum search for Kozaburo should turn it up. Assuming you can't get someone like Little Dragon to produce it on request... :) This isn't a persistent problem, either. It seems to vary between systems, version downloaded, phase of the moon, and number of virgin goats nearby. Aside from that, you just have the same lighting issues you have with any Poser model import.
