Heh, nice
Well, Cumu's tool is for offline rendering (e.g. could be run like once a day, requires the game to be shut down to be sure to not kill anything) but is *really* fast at rendering the whole world.
The mod aims at rendering live as players walk around so basically you get a map that is never older than 1 second. In return the full map render command is slow as hell but you should never need to run that if you have the live rendering starting from when you start a new save game.
Oh, yeah, think I forgot to add a release package when updating the ManualDeob-lib, sorry
