fire extinguisher smoke like in teardown game

first of all im using the URP (Universal render pipeline)

I am making a physics game with various physics simulations and i wanted to make smoke like in teardown
also im am a total noob at shaders in unity

something like that

PS this is my first unity forum post

could try with particle system first,
it has option to enable collisions (and sending event into collider object),
so you can detect what object it hits (if you want to put down fire for example).

minimal tutorial,

but i want like that fluffy thing and i want it to be 3d

There’s a volumetric effect tutorial in this official URP e-book , might be a good starting point of your own volumetric smoke particle effect (applying the shader graph to VFX graph with mesh output).

but it is very laggy when i am close to it
