@cthulusan Thanks a lot John!
The crates are not so much supposed to be newer, as made of different wood. Some woods (like oak) darken more when ageing than others (like pine, for instance).
Everything will get dust and grime added in the shaders. This is only the pure colour information.
I agree that the stairs don’t look that good, but I decided not to re-paint them as well. Same goes for the walls;)
The metal bands come out really well, when also plugged into a Bump node; then you can really see the rust!
But, that’s the shading part….
