By the By Rav, I've found 512x512 versions of all the Belts textures. I'm in the process of assembling a pack between homework assignments. Mixed in there are also a lot of source files like a bunch of rust textures as well as .psd project files with nifty sub textures in them.
If you can put them up somewhere I'd be very grateful. I've got all my projects as GIMP .XCFs so dropping in better quality stuff should be easy enough.
What I really need is higher res versions of the pipework. That's a real bitch to upscale.
Spidey: Can't think of a reason I'd need to know anything
