#MorphoHDL is a small language for growing circuits and graphs. You write a recurrent rule that replaces one cell with several smaller cells. The rule is then applied to those cells, and to their cells, again and again. The circuit is what is left when nothing can divide any more.

A little wrangle to transfer weights from one bone (region) to another. I guess it's an edge case in #Houdini #rigging, but also useful to learn how to process capture data using #VEX. gist.github.com/keerah/393d0...

Needed to streamline cutting things in #Houdini. Built this custom #Vellum #softbody #knife cutter. Handles pretty much any pre-fractured stuff you throw at it 😊 @sidefx.bsky.social #sidefx #simulation #3danimation

My first #APEX graph surgery succeeded😃, it's so much nicer when eyelids are following the eyes movement by themselves. Will add this to the next version of my DAZ2APEX tool. Gotta switch to coding this tho instead of digging in that crazy pile of wires. #Houdini #rigging #characteranimation

A tiny addition to my #SOPs to #LOPs AutoMat script that allows switching between the #material sets with one click, especially if you use multiple renderers (or if you don't want to utilize the Collect node for example) Get it from my GitHub github.com/keerah/Houdi... #Houdini #Solaris

Getting some interesting results with #CHOPs for #camerashake. The main idea here is to re-use the positional noise for rotation to simulate the camera's inertia. #Houdini #animation
To achieve this I took the X noise, delayed it for a fraction of second and then springed and gained it to get the Y rotational response. Same for the Y to RX noise. After some tinkering you can get something pretty natural.

To make it even more realistic it should probably be one more noise of higher amplitude with some quantization to simulate more permanent camera shifts.

My #DAZ to #APEX tools for #Houdini 20.5 got quite a few updates meanwhile. Now it includes auto agent setup, a useful #Kinefx retargeting helper, and more QoL and procedural updates. github.com/keerah/Houdi...

Thanks to a sponsorship from @sidefx.bsky.social we've made some big improvements to our USD and FBX downloads for models, as well as introduced a new MaterialX download option for all textures: www.patreon.com/posts/materi...

Diving deeper into the #kinefx constraints Loving how this lives already Even though I am a bit puzzled how I managed to make it work with all these dependencies 😂 @sidefx.bsky.social #houdini #rigging

A little overview of using #transform attribute to precisely control #sweep in #houdini. Just used sweep to model some organic stuff and dove a bit into the mechanics of it. Sweep is actually aware of many attributes, like trans, rot, orient, etc. So you have plenty of options, just read the docs :)

Working on this nice little thing for my local #Obsidian based #projectmanagement. Still #wip but I love it already. This is an interactive chart in Obsidian based on the time-tracking data pulled from #ActivityWatch. Data filtered by timespan and keywords, granular enough to isolate any job track.

Done quite a while ago in #C4D, ready to do even more fun in #Houdini now. Love mechanics! In character rigs things are very typical, and the most of its life comes from the animation, but in mechanics it's all embedded in the architecture itself #motiongraphics #chopper #helicopter #rigging

Testing a fresh #APEX rig. Now fluffy and #quadrupedal. Not perfect but already usable. I am gradually getting a grasp of all APEX components. For experiment I used splines for the spine, tail and tongue. @sidefx.bsky.social #houdini #rigging #characteranimation

How to seriously geek with #Obsidian 🤭 It changed the way I work and learn. I am a huge personal knowledge management #PKM enthusiast. Started using Obsidian.md a few years back and since then my usage of Obsidian has been extending progressively. garden.keerah.com (a wormhole to my vault)
It became something like an operating system for me. From storing CG-related knowledge, daily notes, and my system config with all the data, crosslinks and manuals (on this picture), to project management and health tracking. I can even run code and publish to my digital garden right from Obsidian!The most cool is that it's free, local and includes mobile versions. And you can travel through that beautiful graph of your digital brain extension (on this picture). 

P.S Obsidian recently added a web clipper that makes capturing information from the web soooo much easier.

By the way. Alt text is the way! Each pic can have #alttext of 2k characters in length. Plenty of space to use for a lot of details! #BlueSky FTW!

I still prefer to build all the main stuff in SOPs and then shape it however I want in #Houdini #Solaris. Here's my recent snippet to quickly move materials from SOPs to #LOPs. To make it work copy over the materials into a Mat library and set the shop_materialpath as Partition attribute. (alt txt)
string separator = chs("separator"); // the name of material network in SOPs
string submat = chs("submat"); // the name of LOPs material subprimitive
string mat = split(@primpath, '/')[-1]; // extract the subset name from the full primitive path
mat = re_replace(".*"+separator+"_", submat, mat); // replace the path with the LOPs material path
return mat;

string submat = chs("submat");
string mat = split(@primpath, '/')[-1];
mat = submat+mat; 
return mat;Set shop_materialpath as partition attribute. Houdini will encode the SOPs material path into the GeomSubset name. And then we will use this encoded name to rebuild the LOPs material path.

Ha! Haven't tried it yet, but next time I need a #gif definitely will. "It iterates through every possible optimization combination the GIF format offers to find the absolute maximum quality possible based on the desired input file size."

Bet you never used #Houdini FFT node. This setup was originally intended to be used for geo data filtering but also fun to play around as a generator.
