Hello. I try to load a bmp image and set it to a texture. When i render the model with the texture (using shaders), even though the rgb channels are passed fine, the alpha channel is always 1. When the image is loaded (using readImageFile), the pixel format is GL_RGBA (which is correct). But the internal format is 4, which i cant find where it corresponds.
What do i have to do to read the alpha channel ? I attach only the alpha channel of the RGBA image (as separate png). Thnx.
