And set the trans falloff to zero. I also find that running a displacement channel at about .2 on the hair main texture helps give it realism. See my pic in the wave hair thread. Basically I use: diffuse colour white linked to texture map. diffuse amount 1. specular colour white linked to texture map. specular amount 1 highlight size about .03 Ambient colour black Ambient value 0 Transparency value 1 linked to transparency bitmap Transparency edge value 1 linked to transmap as well Transparency falloff 0 ... ... Displacement .2 linked to texture map.
