As for using the different layers for different things, I remember being shown a…
We used this on the last game I worked on. Had a photoshop doc with layers that looked like this:~mask - gloss <pure red layer set to multiply> [layers composing gloss map] - reflection <pure blue layer set to multiply> [layers composing reflection map] - dirt <pure green layer set to multiply> [layers composing dirt…
