just a basic question. Is there a direct way to in/decrease the brightness and/or contrast of a already loaded texture?
thanks in advance
Well, you can use materials or combine two textures using multitexture, but directly mod the texture brighter/darker… not that I know of. Unless you count render to texture, texture data is final I believe. (I'm likely forgetting something though.)
Ok, so I tried to mix a texture with RGB + Alpha with a simply white texture. But I dont know how to combine the textures in the right way. So my question is about mixing these textures to have finally a map which uses the alpha channel of texture 1 and have a rgb of texture 1 and a custom amount of the texture 2 rgb value to have a custom brightness.
The pasted code adds the two textures but ignores the alpha. Furthermore I dont know how to change the amount of the added texture 2 rgb.
Could anyone help to solve this problem?
