BumpMap -
...
DEPRECATED

bumpmap 1
IsDiffuseBumpMap / IsSpecularBumpMap -
...
DEPRECATED
Specify what kind of bumpmapping this bump map will do: specular, diffuse, or both. These values are ignored if this texture is not a bump map. Default: isdiffusebumpmap 0, isspecularbumpmap 1
isdiffusebumpmap 1
isspecularbumpmap 1
BumpMapScaling -
...
DEPRECATED
Specify a scaling factor for the bumpmap height. If you want higher peaks and lower valleys in the bump map, set the value to be greater than 1. If you want a smoother bump map, set this value to less than 1. Default is set to 1.
bumpmapscaling 1.5
SpecularColor -
...
DEPRECATED
Specify a color for specular bumpmap highlights (RGB). This value is modulated with the bump mapping light's color to produce the final highlight color. Default is (1,1,1).
