recent finding that might be worthwhile to someone who understands this better than me:
changing "ProjectileType" in tf_weapon_particle_cannon.txt from "projectile_energy_ball" to "projectile_rocket" seems to fix the nosmoke mod (ie no massive blast particle) but breaks the weapon. moreover it does not work in casual mode (even though it seemed to work on an sv_pure 2 listen server).

the weapon behaved exactly like a rocket launcher with this change, except it did not need ammo, and still had the alt attack, except this attack just fired a regular rocket after charging.

"ProjectileType"  	"projectile_rocket" // ORIGINALLY projectile_energy_ball

you place it in

/Team Fortress 2/tf/custom/nosmoke/scripts/

all the text files in the downloads go there.

even if this weren't around faceit can just host their own appropriately sized mumble servers https://github.com/mumble-voip/mumble

also probably not a good idea to rely on someone else's free hosting

maybe a choice between faceit-hosted mumble and ingame voice? ideally tf2 would have per-user volume functionality but since it doesn't...

discord does go down once in a while. you cannot host your own discord servers, and depending on discord for the faceit hubs is probably not a good idea. faceit can definitely afford to host mumble servers in the same fashion as tf2center, so i suppose that's the better way to go about it

they both use the same codec, are you sure that's not placebo

i'm of the opinion that if these faceit hubs are supposed to be quick to queue into, it would be best to require use of ingame voice. past experience with mumble was wonky at best, as good as it may be to experienced users, and it's not hard to edit voice_enable 1 into your config
edit: furthermore if you go into faceit with a full-stack team (ie on higher levels or whatever) while on whatever voip you choose to use, there's no issue

new player here, will these FACEIT hubs require their "supporter" paid subscription?
