Just a quick post on how I did the rust and grime on the Necromunda barricades. I have chosen to assume that the paint used on Underhive structures has some serious protective properties, so my starting point was to keep the rust, corrosion, and accumulated grime near the areas where the barricades have been shot up or chopped apart. I also went with the association that there are some seriously nasty corrosives and such just sort of generally around the environment down there, so when that protective paint gets taken off, the resulting effects are pretty extreme.
To this end, I wanted to get some major texture on there, so I started by blobbing on some very heavy dollops of Martian Ironcrust, Ryza Rust, and Stirland Battlemire. I tried to mix them up, so any larger area would have some of each, because rust patterns are rarely super consistent.
I included the Cadian Fleshtone after reading some stuff by Cavalier over at Frontline Gaming. He pointed out that it's actually a kind of weird pastel orange, and showed it as the final highlight on the red on his Dark Eldar vehicles. I figured I'd give it a try here, and was really happy with how it came out.
So yeah, remember, don't be afraid to try out new stuff and experiment with no fixed destination, and until next time, y'all have a good one, y'hear!
