  1. Differential Erosion / Melting simulation

    Wow, thanks! That's a super elegant and computationally cheap solution. And it seems to give a good amount of control over the process through the volume wrangle remap and VDB reshape itself. I have been using a Voronoi Fracture with VDB Morph which is slower to compute and isn't technically an erosion. But it does in a way produce a more consistent result. erosion_test_v1.hip Do you think it is possible to generate a less randomised Worley/Cellular noise to drive the density / VDB Reshape? Some sort of a middle ground between the complete regularity of a Voronoi diagram and irregularity of cellular noise?
  2. Differential Erosion / Melting simulation

    Yes, that's exactly what I've been using as a temporary solution. It creates a similar effect yet the "strands" of matter are hard to achieve using only noise. Maybe I should try Voronoi/Cellular noise inside the pop solver but I haven't been able to map it into 3D, 2D only...
  3. Differential Erosion / Melting simulation

    Thanks! I'll take a look at this.
  4. Hi all! Loads of cool stuff here. I'm looking for ideas/suggestions from Houdini veterans on how to recreate a process of melting or a differential erosion of the material. I have attached a screen cap of the closest example I've found in a video by Christoph Bader/Dominik Kolb called Area Contraction. Also attached a macro shot & GIF of my physical experiment of creating similar structures via melting. Sadly, I haven't been able to find any papers or simulation breakdown examples of Area Contraction or how to replicate it in Houdini. There are so many potential paths to take that I feel a bit lost - is it best to operate in volumes or VDBs? Or should I simply stick to particle solvers? FLIP liquid with attractors? FLIP liquid driven by temperature values (lava, snow, ice shelf tools)?
