Houdini 17 Is Here – A Quickstart to Vellum

Featured Video Play Icon

One of the most exciting features that Houdini 17 introduces is Vellum: A new simulation framework based on XPBD. (Extended Postion Based Dynamics – In essence grains on steroids.) That means stable and fast simulation of (almost) everything softbody: Cloth, Wires and well – softbodies. In this quickstart series we’ll take you through the bare basics of how to get started using Vellum.

Congratulations to everyone at SideFX and thanks a lot for creating this / these awesome tools!
Without further ado here are the tutorials:

    Thanks for the link, i wasn’t able to make it works, 🙂

    Thanks so much for posting about new features and for doing it in the middle of the week, at launch, instead of waiting for your next typical Monday post. I really appreciate the effort.

    When you say “your slow machine” in Part 1, what do you refere to? Hopefully not the Building your own houdini workstation build 😉

      Referring to my other, older i7 machine that’s used for tutorial recording here 🙂

    Hey Mo,

    Thanks for sharing.
    I’d like to know why you chose to go freelance. Maybe you could share some business knowledge. Just to get a general idea what it’s like be a freelancer.
    I’d love to see a conversation like the one you had with Manuel.

    What kind of simulation times are you seeing on these files? I have done a few tests on both Mac with external GPU/Vega64 and PCs with internal GPU. In general using the CPU is a lot faster than GPU and Nvidia HW at least twice as fast as AMD (Vega64 and GTX 970 have about same speed, while GTX 1080 is twice as fast as these). My testing is not conclusive at all but it would be interesting to here your experiences with Vellum/OpenCL.

      In my case, opencl is not ussing at all the GPU despite of ussing last drivers and setting up the .env file

    How did you manage cloth collision bounciness using vellum !??

  8. Flo says

    One question –
    is Vellum supporting multi GPUs – and/or SLI?

    thanks a lot.

      Flo, how did you manage to use the opencl?
      In my case, opencl is not ussing at all the GPU despite of ussing last drivers and setting up the .env file

    Does anybody know how to add pressure in the vellum balloon?

  10. Hi!
    First, you have maybe the best houdini page, I love what you do.
    That said, I need your help.
    I need to simulate poles and cables breaking and interacting.
    Should I use only bullet and different contraints or should I mix with wire solver or vellum?
    Is it possible to mix RBD and Vellum in a single sim whit the both, poles and cables, braking and sharing forces?
    Thanks you very much.

    Thanks a lot for the introduction. Cool videos!
    In my case not sure about the opengl working on my gpu. Can not track any load increase on it.
    Anyway here is some result 😀
