Glowing smoke on object

HI

I’m after creating a glowing smoke shader like the one in the Youtube link below

What would be the best method for doing so? as the asset is no longer available to buy :frowning:
Ideally it would be great for someone to create it so i can learn about how its made but if not then any advise on where to start would be great too!

I would say:

  • Look into using an additive shader for the smoke particles. An additive shader often gives a very cheap ‘glow’ effect, because when multiple particles are drawn on top of each other their colours will be added up, not blended together. This makes them brighter where they are denser, which the brain generally interprets as how glowing objects behave (lots of glowing objects next to each other get brighter)
  • Setup correctly coloured light sources near the smoke, to give the impression that the smoke is emitting light.
  • Emit the smoke in a way that starts bright and moves upwards in a cone, to give the impression it is moving away from the light source (when in fact it is just getting ‘darker’ over time
