channel of the specular map was set to 0.5, then the shininess would be
set to 8. Default 256.
normalScale <x> <y>
- State the X and Y scales of the normal map. This is useful for increasing
or decreasing the "strength" of the normal map, or entering negative values
to flip the X and/or Y values. Default 1 1.
parallaxDepth <value>
- State the maximum depth of the parallax map. This is a fairly sensitive
value, and I recommend the default or lower. Default 0.05.
An important note is that normal and specular maps influence the diffuse map
declared before them, so materials like this are possible:
