That blob of blood is actually his head :P The first two were using acidbath.inc over glossy.inc. I really do want to make my own sometime, but I can't be bothered atm.
I will be updating my include soon. Some big ideas - will have to see how many make it through!
e.g.
Fight ontop of a sky scraper
Individual colours for joints
Damage shades ontop of custom colours
My already partially-updated version (not released) also supports some extra stuff like working with POV-Ray animation sequences. I don't think this part of Toribash is released to the public yet though (I could be wrong!)
