wow. those decals are really great! as are the models I think that those models are more then enough of single concrete pieces for most scenes. If you're using UDK you might consider doing some sort of a smart-ass material that blends in different kinds of textures through vertex painting. Like random paint lines, moss and…
Update: I made a more complex material for the last blocks of concrete. I also made a few extra pillars and decals. But the main thing I wanna show you guys are my modular road assets. The biggest one is 1,200 tri's, so its pretty well optimized. All of them use the same 1024x1024 texture. The models tile PERFECTLY in UDK…
I'll be sure to release one of the HP models so you can dissect how I did it. This was all done in 3ds max procedurally. I used mostly noise and displacement modifiers to make these, and then used polygon cruncher (which I highly recommend everyone buys), to make the low poly. Many of these models share the same texture…
