Since Koz gives his hair away for free, I'm not about to start complaining that he doesn't support Firefly.

However, perhaps he would allow someone to make P5 MAT files for it. Displacement needs to be added to some of his models, and with some you need to adjust the shading rate or they look very frizzy.

But you get to recognize the various problems with using PP MATs with P5 pretty quickly. Soon you'll be correcting it without even thinking about it.
