Smoke and Flash Bang Grenades - Multiplayer

Hello, I just watched your video. And it seems like the smoke particles doesn’t actually go upwards and spread big.Also while emitting, it looks like the smoke puffs are being twisted in a hurrican form (don’t know how to explain it lol). I would like to ask something before considering buying :

  • How much does fps drop when player is near the smoke ? I designed one myself and unfortunately I encountered huge FPS drop while standing near not to mention getting inside.
  • Is there any chance you can implement the effect which your eyes capture a moment when the flashbang pops and fades it out ? I’m trying to implement this myself but if you can then it can save me some time afterwards.
    Thanks for answering
