The quant system comes originally from Doom (or Quake?),

anyhow, a quant is equivalent to one inch (this is the strange system from the guys that also
drive on the wrong side of the road)

1 inch=2,54 centimeter.

So 72 inch are 183 centimeter, wich is the average hight of a male action hero.


You guys should all stick to this measurement, if you want to use your level
in different game, to have the same scaling.
You will also notice, that this is the scaling of old quake maps, if you want to import them.


so 64 quants are 162,56 centimeters, and not one meter.
More important than having a correct meter scale, is to have a correct scaling
of humans, especially regarding the camerapositioning then.
The camera should be then about 69 quants above the ground, to be in the average human
eye position.
