  1. Hi! What is inside the VEX function ocean_sample? What calculations are done there? I'm writing my own C++ displacement because the oceanSampleLayers is very very slowly. I use houdini/vex/include/ocean.h as a reference. But it uses ocean_sample, with unknown code.
  2. Thanks, StepbyStepVFX I was try to realize your idea. It is not clear how to control the type of colliders (compound for pieces with holes). Collisions work with bugs, penetrations. I am trying to fix it... fracture_test.hip
  3. Thanks, pxptpw. Voronoi is more suitable for glass, stone, etc. But what if I need custom cut lines (long, curved) for my plastic object?
  4. Hi! I need make fracture at sim time based on impact data (without prefracture). The point of impact is not known in advance, and I can't make a prefracture. I can do this during the simulation?
  5. Thanks Henry, this is very useful.
  6. Hi! How do I make the global (scene Y) gravity direction for copied l-systems?
  7. Vdb to Field Microsolver

    Don't works in H16.5, linux (Debian). The compilation runs without errors, but compiled otl don't works...
  8. Hi! How do I make instances of deformable geometry with deformer (wire, lattice, …) on the surface of the animated object? I want to do, for example "hair" with a custom geometry, or algae. They should be copied in the animated surface to have minimal memory usage.

  10. Hi! I need to get simulation of the ocean, with waves which would have interacted with floating object (splashes, white water, foam). Ocean surface from Ocean evaluate and splashes from FLIP simulation. But there were problems: 1) Fluid reflected at the boundaries 2) Waves in the flip container do not have same shape with the surface of the initial ocean (ocean evaluate). Desired behavior of fluid has only in the boundary layer. Please tell me where I'm wrong. Thanx. ocean_test.hip
  11. Hi! >>>with this method What method? Tell how you made it...
