Very, very much a WIP right now, I need far more textures which I'm working on. There's nothing I can do about the gantry texture tiling in the wrong place if you look at the gantry from the wrong direction, but it still fits the bill.
EDIT: Just when I was about to go look for an entire mod to change minecraft's biomes so I can change my intended construction map to a mushroom biome to control mob spawning,
Sethbling went and made a filter for MC edit that allows me to do that and released the video showing this just now. What are the odds!
