Cigarette Smoke - Part 3 - Houdini 19


Since a lot of people are asking me about this setup I thought it would be a good idea to update the setup for H19.

The logic is pretty much identical to part 1 and 2.  The differences are the following:

  • Pyro sim : I'm using a more modern Pyro workflow.
  • Cigarette Smoke Setup : I simplified the logic a bit. More specifically I ditched the Smooth SOP inside the Solver, and replaced it with a way faster Point Wrangle solution.
  • Render : using now Karma XPU ! It's so ... so much faster than Mantra. The volume renders just fine in Karma XPU without any shader assignment. I have very briefly and unsuccessfully tried to assign a volume MaterialX Volume shader following these instructions. If anybody succeeds please let me know !
  • Trivia : I've added a couple of fun advection experiments :
    • advecting a grid to see what happens to the UVs (spoiler : nothing good)
    • advecting rows and lines of the same grid.

Please find the hip file here and let me know if you've questions or suggestion.

  1. Hello and thanks for you help, I did try your method, is indeed a good way to have smoke effects.
    Do you know the Josh Clos method?

    He used cracatoa renderer engine to pixel render advected particles and increase the number of instances with a different value of seed (Wedge in houdini).
    The result is incredible..
    I will be happy to have your thoughts about it!
