Jan-Hendrik Müller @kolibril13.bsky.social · 19/09/2026Blender has 2700 operators. I made a jev search, so that you can quickly find them by searching with natural language. #jev #blender 130
Jan-Hendrik Müller @kolibril13.bsky.social · 25/08/2026A scene that I wanted to see for the longest time: Putting a tomographic dataset into a handcrafted physics simlution. And finally, it's possible! 😍 With the help of Lars from @algebraic-ug.bsky.social and Microscopy Nodes @aafkegros.bsky.social we can now render this cell animation in Blender! 092

Blender 5.2 is already incredible, but with with the latest release of Microscopy Nodes by @aafkegros.bsky.social, cell rendering is pretty like never before. extensions.blender.org/add-ons/micr... 0134
Jan-Hendrik Müller @kolibril13.bsky.social · 10/07/2026I recently had the idea: what if we could render Blender node tree graphs in the browser? So I grabbed the open source Blender codebase and asked Claude Code to reimplement the node editor’s node drawing code (originally C++) in React. After 3 days of fine-tuning, it looks great! 🎉 220

Jan-Hendrik Müller @kolibril13.bsky.social · 02/04/2026Did you know that one can put matrices into simulation zones in Blender geometry nodes? E.g. the simulation from the screen recording produces a smooth-follow effect. 010

Jan-Hendrik Müller @kolibril13.bsky.social · 11/02/2026I've been working on a node sharing website, which I'm happy to share today: tree-clipper.com Select a Shader/GeoNodes/Compositor tree, and then it's a one-click import, as you can see in the demo video. The website is connected to a database, so one can even search for specific keywords. 151
Jan-Hendrik Müller @kolibril13.bsky.social · 06/02/2026I just wrote a script for quick .wav background noise removal.

Jan-Hendrik Müller @kolibril13.bsky.social · 12/01/2026I just experimented with a Geometry Nodes sharing prototype.

Jan-Hendrik Müller @kolibril13.bsky.social · 30/12/2025Today, I learned about matrix multiplication in Blender. These matrices contain info for location and rotation, and can be chained one after another.
