First off, I'd like to say great job on this version of Tread. All new, but the interface is quite dynamic and user friendly (once figured out). Anyway, I'm dealing with some scaling issues...how many inches is one quake unit?
Thanks for the nice comments :) That is a good question, but one which probably has an answer out there somewhere on google. The virtual units to real world units is subjective so you'll probably find several different answers to that.
This is as Joe said, subjective, however in the "Quakeiverse" standard convention is 64Units is 2 meters... since that's the height of the player model.
