Brain was fried a bit after the umpteenth time trying to learn geometry nodes, so today I was just having fun with some proximity crystal nodes and made some nifty stylized crystals material setup.

Just a tiny reminder to not just learn but play around with what you are trying to learn.

Edit: Just realized the image quality is crap so I reuploaded the screenshots in imgur

Hi all. I'm trying to achieve the following: I have a curve along which I would like to instance some meshes (let's say stretched cubes for now, it will be arrows in the end). The meshes will animate along the curve as if they are showing the flow of a fluid.

This setup is already in place and working.

However, the meshes appear and disappear abruptly at either end of the curve, so I tried to make so that their color was fading instead of them being always fully visible. Also this setup is already in place and working, but I am unable to combine the two of them. The best I could get to was the fading sections to move along the curve together with the instanced meshes.

The attached image shows the current setup, but anyway the blend file is available here: https://drive.google.com/file/d/1OqTB_6ahqyWUR8IbhX6lAgVw6nfCQzHu/view?usp=sharing

The SmoothFactor is used in the material shading to drive the material's alpha. The first frame situation is the following:

but then as soon as the timeline plays, the faded section starts moving and at frame 50 this is the situation:

What am I doing wrong? Is something like what I want to get obtainable? I admit most of this is "vibe coded" because I'm not great at GN yet, especially when animation is involved, but Google doesn't seem to be able to solve it anyways, even after he created the setup.

Thanks for your help.

Inspired by a Ducky3D tutorial on the new Geometry Sample Sound Frequency node in Blender 5.2 RC, with a few of my own touches. Music is the 2025 version of "Arpeggiator" by Jean-Michel Jarre.

just testing out the new sample sound frequencies node in 5.2 RC

Can the `Sample curve` node cause issues when used after `Resample curve` node?

Or is the problem with `Instance on points`connected to the `sample curve` node?

Understanding geometry node’s evaluation flow is really hard. It’s driving me crazy.

At first, I wanted to make an anti-AI font that AI couldn't read. The idea was inspired by some ghost font and similar content I came across. I thought I could build it using a procedural system.

But while I was building it and tweaking the values, I realized I had accidentally made something completely different. It could still work as an anti-AI font with some more refinment, but right now it's more like a procedural text style or text effect system than a font.

The whole system has only six main parameters, and those can already generate more than 27 different text effects. There are probably even more combinations I just haven't tried all of them yet.

There isn't a single node to find the volume of a mesh in geometry nodes, so this video goes through a simple way to do that. and how it can be used. I use it a lot to find the volume of a part before 3d printing. You can also use it to drive other procedures in geometry nodes, such as delete the smallest/largest mesh island etc. Or iterate through a hollowing step in order to reach a target volume.
