Thread: Storm granular solver

  1. #16

    looks great

    anyone knows how this compares to Houdini ?

    Thanks, Erikals ! Good question, I haven't really looked into Houdini myself...

    It actually blows Houdini away big time!!! (For granular sims of course!)
    I had a project in which I had to do quite a big grain sim which took me couple of weeks doing it in Houdini and I was still not happy with, every change I wanted to do meant re-simulating... about 10-18 hours at a time...
    Then, I stumbled upon Storm. To say I was blown away is an understatement! haha
    Within 2 or so days, I finished the sim after few changes and refinements, exported to LW and rendered with Octane. It's amazing compared to Houdini grains.
    With the new update to Storm, you can actually create something that resemble liquid!!! I have to try that.

    All I need to figure out now, is how to use the data from Storm to VDB in LW.

    Any ideas?

    Cheers!

    hm, this is actually mighty cool news!

    will have to investigate further...

    i was playing around with the LW 2019 DEMO and there's a tutorial on meshing particles with VDB. I couldn't get it to work. But it might be worth trying, importing the particles into LW and then adding htem in VDB with the "from particles" setting ?

    Here's a link to that tutorial : https://docs.lightwave3d.com/lw2019/...openvdb-liquid

    I'm considering this, how's the liquid with character deformation?

  8. #23

    seen here, should be good, if LightWave exports Alembic deformations correctly that is.

    edit; though, final result is not on par with Houdini / RealFlow

    I don't see anything about liquids for Storm. Is that a beta feature right now? If this becomes a multisolver, it would be a great alternative to houdini.

    probably.

    also, as far as i know, Storm won't allow for motion blur in LightWave (?)

    by the way, anyone tried exporting an Alembic file with deformation to Storm (ā la MDD) ?

    if possible, it should work like this >

    Not quite. OpenVDB is more about how to manipulate and convert volumetric datasets of various types, as opposed to doing the actual simulations which generate those volumetric datasets. See https://www.openvdb.org/about/ for clarification about OpenVDB's functional modules.

    It's more of a "swiss army knife" for manipulating datasets that already exist, as opposed to creating new ones from scratch. OpenVDB allows for converting existing geometry datasets into volume datasets, or converting volume datasets into surface/geometry datasets, for example, but in both cases, it's simply converting datasets that originated elsewhere.

    Hope that helps, obviously the OpenVDB website contains much, much more info about OpenVDB capabilities.

    BTW, Storm looks really cool and even has Mac support, at that price I couldn't resist. Another satisfied customer here.
