Free Houdini HIP: Activating Vellum Grains by Color, Part 1 (RMA FIRE)
Original title: Activating vellum grains part 1 in Houdini | FREE TUTORIAL
Overview
RMA FIRE shares this free Houdini project file from part 1 of a tutorial on activating Vellum grains. The technique controls where grains become active by transferring color from another geometry object and using that color value to switch the grains on, useful for sand or powder that only starts moving where something touches it.
The file is a free download from a Google Drive folder linked in the description. A small but versatile trick for art-directing granular simulations.
