I'm trying to render an image with an output that is the pure diffuse colour only. In earlier versions of Blender I would have just used the internal renderer and created emission materials. But, in 2.8 with Cycles or Eevee, there is always a slight noise on the image.
I know the noise is very subtle, but I need it to be a solid colour. I was hoping I could use the compositor to get just the diffuse, but I couldn't figure out how. I still ended up with the noise in the result.
Thanks for your help Dan
