Is it legal in matches etc?

r_lod 2 doesn't really seem to do much, except you see the enemy clearer at a further distance. If the command is available and not blocked by zBlock, UNGL will allow the command, but if it's a command too cheat with then no.

Alters the quality of models at certain distances. The higher the value, the lower the quality.

Value's up to "2" are legal. (As far as I know, zblock blocks anything higher)

Cool, thanks :)
