Quote: Space and time units of the virtual world are the quant and the tick. One quant is one unit in WED and MED coordinates, and therefore one texture pixel at a 1.0 scale. How much inches a quant shall be depends on the relative size of the models. We recommend one inch per quant for person based games (shooters or adventures), and 4 inches per quant for vehicle based games (war games or flight simulators). This way with the same level size you get much bigger worlds. One tick is equivalent to 1/16 second - the average time between two frame cycles on a very low-end PC.
