cg_nomip:

1 - LightningGun shaft
2 - PlasmaGun bolt
4 - Rocket Launcher explosions
8 - Grenade Launcher explosions
16 - Bullets (machinegun and shotgun)
32 - Railgun
64 - BFG
128 - Blood marks
256 - Smoke puffs

i know of those, and they not the ones im looking for, but thanks anyways...

how bout you just use drawgun 3 or smth

I dont think drawgun 3 is working in Q3..

good point, mixing up ql and q3 /o\

For the grenade skin the command is cg_altgrenades "1"
For the explosions does are the values you need, i dont remember exactly how to use them but i think if only want grenade explosions in nomip you should use the value 8.

And cg_lodbias can give your gun model more or less texture.

you add up the nomip numbers to a combination of your liking :)
