Well, it's intended as astroturf. Whether or not it looks like that depends on your point of view, I'd imagine. Personally, I wasn't satisfied with any fabric or carpet textures for such a thing (actually, I don't like any carpet textures AT ALL, they're all striped or weird.). Did I miss an existing in-game one just like this? Maybe. I dunno.
Anyway, it's supposed to be astroturf, but it works for general carpeting too. The detail on it can be easy to miss, it's not very exaggerated or anything. So click the pics to see, or it'll just look like solid color :p
Is that some brady bunch lawn I see?
Or maybe a sports fanatic wants an outside inside room. (This is the default color)
Or just general carpet purposes.
It's kinda eh, I know. I want to do a true pattern but am having difficulty with the color masks, so this is all I've got for now.
