Changing a texture's colour via RGB values:

[Bikerdude]

Can someone remind me if we have a ewiki entry on how to do this..? I am looking to make a bklue version of our glass texture.

 

- textures/darkmod/glass/clear

 

ta.

It seems that all of the methods are multiplication values, so you could use:

 

diffusemap

 

map textures/darkmod/glass/clear

 

color 0, 0, 1, 1

 

(eg. 0% red 0% green, 100% blue, 100% alpha)

 

or

 

diffusemap

 

map textures/darkmod/glass/clear

 

red 0

green 0

blue 1

 

or you could mask green and red:

 

diffusemap

 

map textures/darkmod/glass/clear

 

maskRed

maskGreen

map textures/darkmod/glass/clear

 

or you could add the colored attribute to the material def then use DR to adjust the tint.

These options should all work. I'm not sure why there is such much redundancy.

 

The "rgb" keyword just merges all the color keywords so you control them all at once.

 

We probably should make a subtopic here:

Hmm, tried all of the above and am just getting a black textures in game...

Post your material def please

OK, you are modifying the default def, then you need to multiply the parm values for the milky texture:
