- Color mask dictates what parts of the texture can have color variation. Black = no variation, white = variation. A normally gray wall accompanied with the color mask texture where the wall areas are white will change the default gray texture into one of the different colors in an overlay effect. You can have for example a red tint on the wall but still see the detail in the painted diffuse texture. The intensity and color that is the result of the color mask depends also on what the original color of the area is.
And we will be able to specify a color to be applied in this "variation"... Could this be randomized ??
