Thanks for reply!
but i dont think that will work because the scratches are made with the plugin and uses a procedural noise map to do it.
Therefore i hope i could just bake this as a flat diffuse with scanline?
EDIT:
Figured it out.
Used it as a mask in blend material with one black standard material and one white and both 100 illuminating, i then put a omni in the scene and checked ambient only.
