  1. centered Point per Primitive

    Here is a version using 15.5, which is as far back as I have installed. Often times, these warnings can be ignored (you know if the scene works, hehe). In this case, a fair bit didn't work. @elemnum is a pseudo-variable, which will refer to the point or primitive, depending on the type of wrangle it's running in. Hopefully you can get 16.0/16.5 as soon as possible, there are lots of excellent quality-of-life improvements (i.e. Group Expression). addpoint_perprim_modified_15_5.hipnc
  2. centered Point per Primitive

    This might help get you where you want to go (probably much more clever ways to do this), but this is how I'd approach the problem. There are a few things happening here (uses some ideas mentioned on other point-to-prim-center threads too): Point Generate SOP to add the points, avoiding the creation and deletion of geometry in a wrangle (to create/delete geometry, at some point VEX has to stop threading to do those operations), which probably only matters on larger geometry, but good to be aware of In a Point Wrangle, move the points to their corresponding primitive position Split apart primitives using Facet SOP, with the Unique Points toggle on After the particle sim, use Primitive SOP to transform the primitives using the particle network Group and delete primitives whose corresponding particle is dead You probably would be safer to setup an attribute dedicated to the particle-primitive relationship, but hopefully this helps a bit! addpoint_perprim_modified.hipnc
  3. [SOLVED]ubuntu-restricted-extras?

    I wouldn't guess it would affect Ubuntu at all (I feel like I used to install that package, but I can't recall for sure). You can get a better idea of what it'll provide (since it's a meta-package) with apt-cache showpkg: $ apt-cache showpkg ubuntu-restricted-extras Package: ubuntu-restricted-extras Versions: 65 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-amd64_Packages) Description Language: File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-amd64_Packages MD5: 5625deefba56f767d8e27098e82e3e9d Description Language: File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-i386_Packages MD5: 5625deefba56f767d8e27098e82e3e9d Description Language: en File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_i18n_Translation-en MD5: 5625deefba56f767d8e27098e82e3e9d Reverse Depends: ubuntu-restricted-extras:i386,ubuntu-restricted-extras Dependencies: 65 - ubuntu-restricted-addons (0 (null)) ttf-mscorefonts-installer (0 (null)) unrar (0 (null)) libavcodec-extra (0 (null)) ubuntu-restricted-extras:i386 (32 (null)) Provides: 65 - Reverse Provides: And if you look into ubuntu-restricted-addons, it lists more codecs: $ apt-cache showpkg ubuntu-restricted-addons Package: ubuntu-restricted-addons Versions: 23 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-amd64_Packages) Description Language: File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-amd64_Packages MD5: d4aa4cd0f0f949dc257017988928544e Description Language: File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_binary-i386_Packages MD5: d4aa4cd0f0f949dc257017988928544e Description Language: en File: /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_xenial_multiverse_i18n_Translation-en MD5: d4aa4cd0f0f949dc257017988928544e Reverse Depends: ubuntu-restricted-extras,ubuntu-restricted-addons ubuntu-restricted-addons:i386,ubuntu-restricted-addons Dependencies: 23 - gstreamer1.0-plugins-ugly (0 (null)) flashplugin-installer (0 (null)) gstreamer1.0-plugins-bad (0 (null)) gstreamer1.0-libav (0 (null)) gstreamer1.0-fluendo-mp3 (0 (null)) chromium-codecs-ffmpeg-extra (0 (null)) oxideqt-codecs-extra (0 (null)) ubuntu-restricted-addons:i386 (32 (null)) Provides: 23 - Reverse Provides: So if you want to avoid non-codec stuff, you can just install the gstreamer and libavcodec packages. That'll leave out the rar, font, and flash packages. Hope that helps!
  4. Duplo Bear via Bullet Constraints

    Here is a breakdown of how I made this bear made out of duplo blocks: The video isn't super comprehensive, I mainly cover setting up the constraints in SOPs, though I briefly touch on some other parts too. But the hip file is available to pick apart! Thanks! duplo_bear.zip
  5. There is HOUDINI_UISCALE, which is a percentage scale (so 100 is normal).
  6. Try using the Surface Constraint on your animated mesh; it can constrain to a position inside of a primitive, so you don't need more polygons. surface_constraint.hipnc
  7. Arnesen Cubes in Houdini

    Thanks Matt!
  8. Arnesen Cubes in Houdini

    Christian Arnesen did an awesome piece of animation with MASH, and I wanted to replicate it in Houdini: Here is the breakdown of 3 techniques for doing so, using Alembic caches, Copy Stamping, and VEX (file is attached below or at the link): Hope it's helpful! arnesen_cubes_in_houdini.zip
  9. This came out of the blue, very surprising! Hope everything works out for the team. http://fabricengine.com
  10. You can just edit the title ad add [Solved] or something like that. You never know when someone else will have the same question, no matter how trivial it might seem.
  11. The question about HQueue

    You’ll need to point it at a drive that has sufficient space; if you don’t have a larger D:/ drive, or other drive, you’ll need to add a large hard drive and change your server to point to that. I’m not very familiar with HQueue under Windows, but this link for editing the shared folder should get you started: http://www.sidefx.com/docs/hqueue16.0/help/faqs#how-do-i-register-a-shared-folder-with-the-hqueue-server Hope that helps!
  12. Random link of interest

    Very cool website on solving different problems in different programming languages, like Cholesky decomposition https://rosettacode.org/wiki/Rosetta_Code
  13. I'm on Mint 18.2, and I haven't noticed this; are you talking about Alt + clicking moving windows?
  14. I like to connect trailed points (or particles) then polywire those curves, to get smooth emission from fast geometry. Something like this, but I'll have velocities on the geometry, and noise it up sometimes to break up the shapes a bit further. When going this route, sometimes you have to dial down how much density is emitted on each frame; if there is a lot of overlap, it can dump too much density and cause a lot of expansion and slowness. fast emitter.hipnc
  15. I found these on GitHub; the author is using MSS_ReusableSelector: https://github.com/sebastianswann/hou-hdk-sop-straighten https://github.com/sebastianswann/hou-hdk-sop-perfectcircle https://github.com/sebastianswann/hou-hdk-sop-edgelength These aren't quite like the PolyExtrude manipulator, but maybe they'll be helpful in figuring it out. Good luck!
