Please, edit your posts. It's hard to read when you have 4 posts in a row. Bit it's bad to not have any hint brushes or any detailed brushes. If you have any barrels, crates etc. that don't block visibility, select them all, opec surface properties by clicking S, check detail box, click set content and then add content (or other way around, im not sure, i just click them like 20 times...) And there's some tutorials about VISing. There is Dag's tut on forum and also on RUST. I dont have time to put links.
