  • Bringing in a custom hitting object
  • Organizing your network for best workflow
  • Tweaking constraint and material properties
  • Creating intra-material constraints
  • Using multiple constraint types
  • Configuring glass for rendering
  • Debugging and tweaking simulations

    This is Houdini 18.0.287? I suspect that the example HDA is not in your install. If you can, please try the latest daily build.
