I edited the length of time the SmokeGun mod's particles lasted, and it supplements fires perfectly! Makes fighting fires a ton more realistic and fun. Tutorial and my PC Specs BELOW ​(click show more):

SmokeGun Mod Tweaked Code (I do not take credit for mod, just edits):

GO TO Steam\steamapps\common\Teardown\mods\smokegun

EDIT the main.lua file in notepad (PLEASE BACK UP THE FILE)

Find and paste below into the file BE CAREFUL

Set up the particle state
ParticleReset()
ParticleType("smoke")
ParticleRadius(radius)
ParticleAlpha(alpha, alpha, "constant", 0.1/life, 150.5) Ramp up fast, ramp down after 50%
ParticleGravity(gravity * rnd(0.5, 1.5)) Slightly randomized gravity looks better
ParticleDrag(drag)
ParticleColor(red, green, blue, 0.1, 0.1, 0.1) Animating color towards white

Emit particles
for i=1, count do
Randomize position slightly. This is important when spawning multiple particles at the same time
local p = VecAdd(pos, VecAdd(VecScale(dir, radius), rndVec(radius)))

Randomize velocity slightly
local v = VecScale(VecAdd(dir, rndVec(0.2)), vel)
Include some of the movement of the attachment body
v = VecAdd(v, VecScale(GetBodyVelocityAtPos(emitBody, pos), 0.5))

Randomize lifetime
local l = rnd(life*120.5, life*240.5)

Spawn particle into the world
SpawnParticle(p, v, 60)
end
