I worry that it may confuse or that I’m the one confused…
But according to physics there is no diffuse coloring component in metal as stated in the video…
If I’m right maybe the confusing statement could be removed?
The only thing that varies is the structure of the surface, such as the roughness depending on wear.
Only other material, such as dirt can actually give a diffuse component on the material, which is always true of course.
