A set of Common and Afghan Props I made for Project Reality back in 2011. The texture setup is a bit odd as it uses the Refactor Engine's Static Texture system which has multiple texture layers on different UV Channels for "Colour", "Detail", "Dirt" & "Crack" Textures. For example, the Rug texture uses it's main colour for the overall colour of the rug with the pattern, but it then overlays the Rug's separate detail texture on another channel that is tiled multiple times to provide that close up detail you can see up close, and the detail also has a normal and spec texture to go with it. Then on top of that, you can add a dirt texture to add a bit more variation to the colour and a crack texture to add decals.
These textures were made to make PR's props have a common set of textures all on the same atlas/palette to reduce draw calls and texture memory needed to be loaded, although in hindsight with my knowledge now I could vastly improve on optimisation if I was to do something like this again.
