5 Tips for Realistic Smoke in Houdini Pyro

Quick advice on shaping volumes, lighting density, and rendering smoke simulations that don't look fake.

Realistic smoke is mostly about restraint. Five things I keep coming back to when a Pyro sim looks plasticky.

  1. Drive density with temperature falloff, not sourcing tricks.
  2. Light from behind first, fill last.
  3. Use OpenVDB to break up the silhouette.
  4. Keep your render frustum tight — voxel waste kills detail.
  5. Comp pass-by-pass; don’t trust beauty alone.
