ive been looking through my textures and i cannt seem to find a transparant of the steel cables that you get inide reinforced concrete if anyont has seen any please tell me what section it is under

Under textures, global_use. It's called metal_masked@rebar.

ok thx i will check it out!

There's also a couple of textures in industrial. There are a bunch of bar/fence ish textures that show up twice--once to the very top of the texture group and once again towards the bottom. They're available in a bunch of sizes and resolutions, but my prob is that there are two sets--one set shows us with a black filled background in the texture window (in graydient), and the one towards the bottom has a clear background. I've used the one with a clear background and obtained the effect that I want, but I was wondering what the black background one was for.

If you're using steel cabling, the ones toward the bottom look pretty good. I think it just looks better for more modern destroyed concrete structures like bunkers and stuff.
