seta r_lodbiasskinned "0"//Level of detail of skinned objects (-1000=better to 0=lowest)
seta r_lodscalerigid "4"//Level of detail of static objects (1=best to 4=worst)
seta r_lodscaleskinned "4"//Level of detail of skinned objects (1=best to 4=worst)
for maximum quality
seta r_lodbiasrigid "-1000"//Level of detail of static objects (-1000=better to 0=lowest)
seta r_lodbiasskinned "-1000"//Level of detail of skinned objects (-1000=better to 0=lowest)
seta r_lodscalerigid "1"//Level of detail of static objects (1=best to 4=worst)
seta r_lodscaleskinned "1"//Level of detail of skinned objects (1=best to 4=worst)
