Im having problems with modulating my texture. Im implementing a cloud system, where I use texture splats on several quads setup in a particle system. When I apply the texture splat, I eighter get an output where the texture is applied to each quad, and they are not blended together, or I get an output where the splats are blended just fine, but they are white all the time, no change in color, eventhough the color set changes. Im using GL_BLEND and the GL_MODULATE option in glTexEnvf. Please reply if you have any idea about what im doing wrong, or if you need more information to help me.
