Free Houdini HDA: Point Infection Solver v1.3 with Demo Scene (Ivy M)
Original title: Houdini HDA demo point infection solver v1.3 (free download)
Overview
Ivy M demonstrates version 1.3 of a point infection solver HDA and links the files on GitHub for free download. The solver spreads an infection over geometry to generate wet map, burning, spreading, footprint, mark and dirt masks based on animation, and both the infected geometry input and the optional infect source points input can be animated.
It outputs a falloff attribute as a spreading mask and an edge attribute for the growing area, which the README suggests binding to a shader or treating as a pyro source, with options for noise and threshold cleanup. The repository holds sop_Y24i_point_infection.1.3.hdalc and the demo scene sop_Y24i_point_infection.1.3_DEMO.hiplc; the README notes that the HDA does not work in Unreal Engine through Houdini Engine.
What You Can Learn
- Grow wet map, burning or dirt masks over animated geometry from infection source points
- Use the falloff and edge attributes as shader masks or as a pyro source
- Open the demo scene to see the solver set up on an animated input
What you get: HDA (.hdalc, .hiplc)
