I am trying to save a grayscale EXR image. I created the image in Krita using the 4096 x 4096 32 bit grayscale profile I chose when I started. When I'm working on it, it has a gray channel and an alpha channel. When I save it as EXR and reload it, it has RGBA channels and appears green in color because the green channel is white, and the blue channel is black. The red channel contains my grayscale image. Is there a solution to this? Am I doing something wrong? When I save in other formats it's fine.

I'm a newbie at Krita. Is there a way to delete channels like I can in Photoshop? Or draw just in one channel? Can't I edit the alpha channel?

Thanks.

I still haven't found a solution to this. It's hard for me to believe that this is a problem that nobody has encountered before, since grayscale images are used as displacement maps in all 3D software.

Can this be fixed?
Thanks.
