That's weird..
If you ignore the fact i put a green grid on it as a second pass
material preset_8_eyeMatL
{
technique
{
pass
{
cull_hardware none
cull_software none
scene_blend alpha_blend
specular 0.447059 0.498039 0.454902 1 61.44
texture_unit
{
texture preset_8eyeL.png
}
}
}
}
i ended up with transparent teeth. Well, only were they were supposed to be. Without the scene_blend alpha_blend part they looked like charcoal like you said.
