How can I create an RGB mask using blender?

I was wondering if anyone has found a way to do this. I’m aware that you can create a color ID map in blender for programs like substance designer and such. However, this creates color images and not the RGB channel images that unreal needs. If not, are there any more automated ways to do this? Photoshopping the UV images is such a chore that is just itching to be simplified. Thanks for any help!

Blender is a modeling/sculpting/animating program it isn’t built to do what you want. You need to use a photo editing tool like gimp or Photoshop. You can look at blenders cycles compositor to see if it’ll output color channels and then save those images as separate color channels but seriously I’d stick with Photoshop.
