Layers to Channels?

Hey everybody!

I was wondering if its possible in gimp to make a new image from 3 input layers which are mapped to individual channels.

For example,
I have 3 layers

Is it Possible to create a new image from these 3 layers where each layer is one channel,
Roughness = R
Specular = G
Metal = B

I hope I made clear what I mean.

Now I feel dumb. I looked into the menu a bunch of times and compose was always greyed out. I now figured out I have to set the image manually to grey-scale. Now it’s working just fine.

Thanks for the fast reply! :slight_smile:
