[SOLVED] Is there a way to disable 'only' projectile trails?

Rocket's smoke is annoying that distract my aiming.
I know there's 'Particle' options that can disable this. But it also disables explosion effect and I want this enable.
When I play Quake Live, it is simply solved by typing "seta cg_noProjectileTrails 1". I tried this on Xonotic but nothing happen.
Is there a way to do like "cg_noProjectileTrails 1"?

Check here for more granular options http://xonotic.org/tools/cacs/#0a/0/particles

but I think this will do what you're asking:

cl_particles_smoke 0

That is what I'm looking for.


Thanks.
