Thanks April, I can get most hair to work fine in P5 with firefly, but the only problem I have not been able to fix yet is when the geometry itself causes a conflict (such as in some Neftis hair). For some reason Firefly locks up when complex overlapping and intertwining geometry is rendered. So if your hair renders at all, I'm sure it is fine with P5 - the rest is just a matter of adjusting the shaders. Thanks again for the help. Nice work on the hair :-)
