MULTIPLY[edit | edit source]
Multiplies the colours to the two textures, generally making them darker. If the second texture is white, then it has no effect, since white means multiplying by 1.
MULTIPLY_X_2[edit | edit source]
Multiplies the colours of the two textures, and then multiplies the result by 2. This is basically the same MULTIPLY, except that you can also make something brighter this way. A grey texture (rgb 127) has no effect. Darker than grey makes the result darker, while brighter than grey makes the result brighter. The result is that MULTIPLY_X_2 can be used kind of as a combination of both MULTIPLY (darker) and ADD (brighter) at the same time.

GRADIENT_MAP[edit | edit source]
Gradient map is a SecondaryTextureOperation: it combines two textures. It can be controlled through secondaryColour. This is what its values do:
- Red/Blue: levels effect, similar to Levels in Photoshop. Set to red=0 and blue=255 for default.
- Alpha: fade between modified colours and original colours. Set to alpha=255 for full effect, or alpha=0 for no effect at all.
