    Hello , my problem is I have a smoke particlesystem spawn as SubEmitter of the parent Particle System.
    My smoke is spawned on a circle. When camera run into the smoke circle , gpu alpha blend in pixel size is very large . So I wanna to cull the subEmitter smoke when the subparticle is too close to camera .
    Is there a way to do this ?
    each subemitter particle is a small smoke


    when camera run into the smoke , the near particle smoke is very large .

    One way is to set the max particle size in the renderer module. It will shrink particles as you get close to them, to prevent the massive fill rate problem you describe.
