  1. Smoke Solver | Tips and Tricks

    Good point. Something I have to improvise I guess. Initially I wanted to but was lazy, easier to put a setup than writing. I'll consider in future though!
  2. Smoke Solver | Tips and Tricks

    Filament like structure, combination of Smoke Solver, VDB Advect Points + Volume Rasterize Particles. smokesolver_v3.hipnc
  3. Smoke Solver | Tips and Tricks

    Another, focused on instancing smoke objects. Manipulating points with basic instancing attributes, i@cluster, v@scale and f@sourceframe. How to activate smoke object and holding a volume source. This method ideal for triggering independent gas simulation on impact data. Additional examples, e.g. grid clustering method for trail and non-trail which I'm merging from a separate thread. smokesolver_v2.hipnc
  4. Smoke Solver | Tips and Tricks

    Subjective question, at least this how I started: 1. Shelf tools, learn the basics and concepts. 2. Dive into DOPs OTLs/HDAs and look around to see how they are implemented. My examples are just a product of what those Side Effects guys implemented. 3. Read Houdini's documentation. 4. Be inspired by all the test that posted on Vimeo/YouTube that doesn't look like off the shelf imagery.
  5. Smoke Solver | Tips and Tricks

    Few tips and tricks to manipulate gas simulation. 1. Independent resolution grid. E.g. Overriding vel grid size independent to a density grid. 2. Creating additional utilities. E.g. gradient, speed, vorticity and etc which can be used to manipulate forces. 3. Forces via VEX and some example snippets. smokesolver_v1.hipnc P.S. Some of this technique are not Open CL friendly though.
  6. Smoke/Pyro | Cluster Simulation

    An example of grid clustering. cluster_v01_01.hipnc
  7. Help achieving Sharp and Thin Smoke Details.
