# Ns = Phong specular component. Ranges from 0 to 1000. (I've seen various statements about this range (see below))
# Kd = Diffuse color weighted by the diffuse coefficient.
# Ka = Ambient color weighted by the ambient coefficient.
# Ks = Specular color weighted by the specular coefficient.
# d = Dissolve factor (pseudo-transparency). Values are from 0-1. 0 is completely transparent, 1 is opaque.
# Ni = Refraction index. Values range from 1 upwards. A value of 1 will cause no refraction. A higher value implies refraction.
# illum = (0, 1, or 2) 0 to disable lighting, 1 for ambient & diffuse only (specular color set to black), 2 for full lighting (see below)
# sharpness = ? (see below)
# c
# map_Bump = Bump texture map.
# map_d = Opacity texture map.
# refl = reflection type and filename (?)
