My question is simple: does Blender support texture where RGB is color, and A is a grayscale texture (not transparency)?
The image file can be PNG or TGA, both with straight (aka unassociated) alpha, and all I want is to extract that alpha, without affecting the color channels.
So far, I have tried every "color space" + "use alpha" setting combination, and none can give me both a straight alpha and correct RGB color:
- I can pick sRGB/Linear without alpha, then I got RGB channel right, but A channel is all white.
- I can pick sRGB/Linear/Non-color/Raw with alpha, then I got A channel right, but all black in RGB channel.
And this only affects Render view. Material view is somehow happy either way.
