This week I made two small patches of rubber moss for Necromunda. Rubber moss is one of the more unusual lifeforms found in the Underhive - like the ash clams in my previous post, it is not directly lethal, but has the bizarre defence mechanism of being extremely unstable & bouncy :-> If a model moves faster than 2" across rubber moss (or falls onto it), it is sent D3" in a random direction (potentially off a ledge/into a wall/into something nasty/onto more rubber moss!)
I made my rubber moss by sculpting a thin layer of Green Stuff putty over some urban debris bases, letting it tear in the middle to expose some of the base. When I started painting, I wasn't sure what colour it should be, but my friend Tim suggested a lurid mix of blue, green, & red. I began with a sea-green, & it quickly developed into what you see here, fading from turquoise at the edges, through sea-green, to ultramarine. I gave the moss a coat of gloss varnish to emphasize it's rubbery-ness. I imagine it as slightly bioluminescent in the gloom of the Underhive.
