  1. RDB object and Vellum Solver affecting eachother

    Try using search before asking:
  2. Ways to deal with RBD "popping"(?)

    Yes transform node before dops
  3. Ways to deal with RBD "popping"(?)

    If you have a lot of small pieces often helps to scale up 10 times before dop. Bullet has a problem with small objects. Do not forget to scale up all forces and physical parametrs.
  4. Usually original points in group with name as the emitter node name and points from replicate in group with name as the replicate node name.
  5. Simply pin a RBD on an animated mesh (alembic)

    Glue constraint works with animated objects, all other not
  6. Reading .env file from a centralized directory

    Packages dir reads before env file, so you need to put json files in each houdini folder or use a wrapper )
  7. particles along surface: surface moves??

    You can do it like this. pop_moveGeo.hipnc
  8. Vellum- collapsing tree-

    Vellum still not best way for simming hard objects. Better use wire sim. More stable more predictable.
  9. Curveu Noise

    You need to find the way to not change topology. Without it will be hard to make procedural setup
  10. [SOLVED] Tree Sim Deform

    Sweep used normals along spline and up vector to orient shapes, by default after dopnet you have orient attribute you need to delete. Use foreach per branch to create shapes and then use it in point deform. In my vol3 tutorial you will find explanation of all aspects of the meshing.
  11. [SOLVED] Tree Sim Deform

    To use curves for deform you need to create geometry using sweep from curves and then plug to point deform.
  12. FEM freeze

    This picture show nothing. Can you provide scene? Why you use FEM for it, better use wires
  13. Retiming VDB vs Retime houdini volume

    To interpolate VDB vel you need to separate vel for three floats x y z. And you need have only density and vel, if there are more floats channels retime will not work.
  14. Matrix and quaternion to degrees problem

    In your case you can make all much simply cogs_automation_problem_fix.hipnc
  15. vdbsegmentbyconnectivity gives what you need.
