no except having 12000 pk3 in one of your folders ( but then it's buggy bug time )

r_ignorehwgamma 1 will make the rocket & explosion look smaller

have this already.

its r_ignorehwgamma 0 for me, you'll know if its working because your hud will darken out

damn.. ignorehwgamma 0 makes everything to dark. tnx for help anyway guys..

Adjust scene intensity through bloom settings (I have bloom intensity at 0 and scene intensity at 0.375) and set the overbright bits to high, do the same for map overbright bits. The game won't look great but at least the weapon effects will look semi-transparent.
