  1. Is there any explanation how import external script to the python panel in H19 and python3.x? Looks like old solutions for python2.x doesnt work any more. I created widget in designer and want to add it to python panel but got error.
  2. removepoint problem

    Because removepoint cant remove primitive if it has points on it.
  3. Dynamically Adding Geo to Vellum solver

    use vellum source and turn continuous mode
  4. RDB object and Vellum Solver affecting eachother

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

    Yes transform node before dops
  6. 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.
  7. 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.
  8. Simply pin a RBD on an animated mesh (alembic)

    Glue constraint works with animated objects, all other not
  9. 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 )
  10. particles along surface: surface moves??

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

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

    You need to find the way to not change topology. Without it will be hard to make procedural setup
  13. [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.
  14. [SOLVED] Tree Sim Deform

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

    This picture show nothing. Can you provide scene? Why you use FEM for it, better use wires
  16. 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.
  17. Matrix and quaternion to degrees problem

    In your case you can make all much simply cogs_automation_problem_fix.hipnc
  18. vdbsegmentbyconnectivity gives what you need.
  19. Tubes to curves

    Something like this. lineFromGeo.hipnc
  20. Copy stamp

    Create orient attribute per point and use copy to point SOP.
  21. Procedural Tree Rigging System and Dynamics complete Bundle! Save 17% buying all three volumes! https://bit.ly/2LC3rPv
  22. I released tutorial about procedural tree rigging system. Applying for any model. Procedural setup of the wire dynamics, non simulation wind system and growth setup working in real time. Capture geometry by spines. https://gum.co/Xxeqf I hope you'll like it.
  23. Instancing tree leaves?

    You should build matrix fort static leaf and rotate this matrix by matrix from the nearest point on branch.
  24. Procedural Tree Rigging System and Dynamics Bundle - complete tree rigging tutorial series! https://gum.co/UpRQf
  25. orient grids to origin by edge

    Yes normals can be in different directions, if you need one direction you can use normal vector in building matrix. orient plane_fix.hipnc
