  7. Point VOP error on Ubuntu

    Hello, I had a similar issue recently on ubuntu mate 16.04.04 lts. I could not get Attrib VOPs from scenes from different builds working and it was very buggy. I always got Vex error ;_name@ Undefined op code Failed loading function Unable to load shader. I was also getting No LSB modules are available. error message after starting Houdini (16.5+) into terminal. LC_ALL = C setting did not help me, but what solved my issue was to install lsb-core package and reboot. So on ubuntu simply run: $ sudo apt-get install lsb-core and reboot. I am posting it here in case somebody has similar problems.

  12. pluralize vex

    Seriously? http://www.sidefx.com/docs/houdini/vex/functions/pluralize Can we get a function that will translate things into another language? Or maybe a spell check?

  19. Hello, I'm playing with bullet dynamics in Houdini. But I'm having quite often one problem - strange motion in e.g. small shards on ground plane. They don't stop moving even after few seconds after they fell on the floor. They are not changing position but just slightly rotating. This motion seems to go on and on... According to docs Linear/Angular Treshold parameter in RBD Packed Object should fix it, but it doesn't seem to have any effect. Have you experienced this type of error and if - have you solved it? Thanks

    Hello, I AM DYSLEXIC - a very nice student project I worked on back in 2015 just got published, I did FX for it, all in Houdini, then handed over caches to lighting and rendering guys (rendered in Mental Ray in Maya). I really like visual style and it was really interesting to do some effects for this style of animation. Enjoy Short breakdown: 00:48 - paper (cloth) sim, a proxy collision geo of hero character was animated and used for interactions 03:22 - RBD simulation advected by hand-drawn guide curves and underlying FLIP simulation, some VDB meshes for hill filling, procedurally generated pages between books with fake dynamics (even though they got totally lost in the renders)

    I wrote a guide on writing simple node operating on OpenVDB volumes in HDK: Creating simple C++ OpenVDB node in HDK What it does is basically: the node will take a VDB volume as an input and point cloud, then at position of each point it will activate matching voxel in VDB volume. You can also check repository with the code: VDB Activate from Points

  24. über slow

    I was just wondering about the same thing, it is quite slow from my side as well.

    adding project files, it is a bit messy because it contains all my nodes for exploring the techniques and testing out things, but still might be helpful for some some paths are hardcoded but with a bit of fixing you can get it running gridless_selma.hipnc
