In the render below, you can see the organels of a marine plankton, measure by an electron microscope. 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...

It’s a read-only viewer for now, but the layouts come out properly Blender-styled. Super happy that it already found a home in the documentation page of Brady’s new nodebpy module. Link to the docs: bradyajohnston.github.io/nodebpy/node... And here’s the react component: github.com/kolibril13/g...

I 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! 🎉

Just made some explorations in the compositor and came up with 3 new nodes: Average Color, Round Corner, and Drop Shadow tree-clipper.com/jan-hendrik/... tree-clipper.com/jan-hendrik/... tree-clipper.com/jan-hendrik/...

Google has recently released a free new JavaScript Gesture Recognizer, and I've just wrapped this into a Blender extension. Full blog post with installation instruction here: jan-hendrik-mueller.de/blog/gesture...

Blender Burn Simulation! Made with Geometry Nodes + Simulation Zones

Jan-Hendrik Müller @kolibril13.bsky.social · 02/04/2026

Did 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.

Jan-Hendrik Müller @kolibril13.bsky.social · 24/03/2026

I just wrote a short tutorial on speed-dependent Grease Pencil motion trails in @blender.org (Geometry Nodes). Enjoy! jan-hendrik-mueller.de/blog/animate...

Yep, DADGAD is so convenient for Folk music! lovely tune by the way!

I'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.

I just wrote a script for quick .wav background noise removal. Takes about 2 seconds to run, and completely command line based: github.com/kolibril13/u... Under the hood, it uses the open source package "noisereduce" github.com/timsainb/noi...

Jan-Hendrik Müller @kolibril13.bsky.social · 12/01/2026

I just experimented with a Geometry Nodes sharing prototype. A webpage with a thumbnail and a copy button that copies a Base64-encoded node group, which can then be pasted into Geometry Nodes using Tree Clipper (by @algebraic-ug.bsky.social, released a few days ago). What do you think about this? 💭

Full Camera Control with Geometry Nodes

YouTube video by Jan-Hendrik Müller

Jan-Hendrik Müller @kolibril13.bsky.social · 30/12/2025

Today, I learned about matrix multiplication in Blender. These matrices contain info for location and rotation, and can be chained one after another. Super useful with the new "Geometry Attribute" constrain, e.g. to make a camera follow an object, like in the screen recording

Two years ago, the donut tutorial used just texture paint, today we have got displacement maps from real scans! 🍩

Thanks for sharing! Will this make it also possible to install multiple versions of one package into the same virtual environment?

I just released a new Blender extension for blurring images and scene backgrounds: extensions.blender.org/add-ons/blur... Under the hood, it uses the image processing libraries PIL and OpenEXR.

Jan-Hendrik Müller @kolibril13.bsky.social · 13/08/2025

Keep us updated how it works, looking forward to seeing what you re up to

Useful trick for VS Code / Cursor AI: Make a custom settings.json file for a project scope. E.g. I'm using this snippet to format my JSON files in a convenient way.

Jan-Hendrik Müller @kolibril13.bsky.social · 04/07/2025

Today I learned that Blender supportes fuzzy search, e.g. “iop” for Instance on Points. Useful and very stable shortcuts.

Jan-Hendrik Müller @kolibril13.bsky.social · 14/06/2025

In Blender 4.5 (coming next month), it will become much easier to add Grease Pencil Text. Here's the new "Faces" option for the "Mesh to Curve" node in action.

Jan-Hendrik Müller @kolibril13.bsky.social · 24/05/2025

Data driven workflows will see many improvements in Blender 4.5!
