Multitexturing with a Detail Texture
Author
I have been trying for ages to use a detail texture with a procedurally generated texture to get a nice smooth effect on a terrain but am having trouble getting the right texture modes to perform the desired effect.
I am doing:
glEnable(GL_TEXTURE_2D);
textureManager->Use(0); //detail texture
pglActiveTexture(GL_TEXTURE_0);
glEnable(GL_TEXTURE_2D);
textureManager->Use(1); //generated texture
pglActiveTexture(GL_TEXTURE_1);
Then I've tried a whole load of modulation, combine, add_rgb functions and none of them seem to give the desired affect. What modes would be required?
If i've not given enough information, just ask and I'll post it.

What effect do you desire? [smile]
If you just want to use a normal greyscale detail texture modulation should work. Just load the greyscale texture with GL_LUMINANCE or GL_LUMINANCE_ALPHA format and the color modulation should be luminance * color (i.e. detail texture * generated texture)

RGB effect of the generated texture with the detail (in terms of bumps) of the detail texture.
