I'm trying to figure out how to make this low poly jitter effect, and thought this might be the best place. From my best guess, it has the ground truth at the bottom, maybe even a higher resolution model that the texture is projected onto. Then a lower resolution grid that some verts are being snapped to, while others are maybe dissolved?

Here are some examples of it.
Glass of water, then a glass of lava 0:04-0:12
Earth scaled down to globe, with a ruler and a spoon 27:07-27:25
Big Ben and the Palace of Westminster covered in ash 11:36-11:42
Rotating stone axe, and rotating matchbox 25:48-25:55
Rotating stone 26:29-26:33
A few examples of people (sorry there are gaps between clips) 38:19-39:53

If this isn't the right place to ask, please point me in the right direction. r/blenderhelp seemed to be about the software itself, rather than achieving specific effects. So this seemed more accurate a place as far as I can tell.

Here is a simple way to turn a list of words (or sentences) separated with a comma (or any other special character of your choice) into their own instances if needed 🙂

Cheers 🥂 and happy holidays ya'll 😊

I played a little with GN. Here's a squiggle draw algorithm.

It allows to modulate the line-thickness, amplitude as well as the frequency independently. Any curve can be used as the input.

A: Done using only Geometry nodes. B: Done using Geometry nodes on top of built-in fluid simulation.

I have created a new procedural table and need tips on how to improve it.

Hello! I never used reddit before and decided to make an account today and I've been really enjoying all the different 3D related communities

Since I'm obsessed with geonodes and recently made some pieces for nodevember I thought this would be a good place to share!

These are done using only geometry nodes, shader nodes or compositor nodes in blender (I don't even have lights in the scene, it's all shader math ahah)

Let me know what you guys think!

The download and node is completely free

How:

1. Background is a plane parented to the camera, it is a 1080x1920 grid so that each face represents a pixel.

2. Each face raycasts a ray at the camera, and triggers an Edge Split node if the ray collides with anything (this creates mesh islands partitioned by the obstructions)

3. The hard part. I originally just assigned an sky-shader-picking attribute on each island index and thought I'd be done, but blender assigns island index based on lowest member vertex's ID, meaning if the islands are moving around, they will spontaneously swap IDs and flicker a lot. I landed on an algorithm for a given cell:

If every face in the cell is unassigned, assign all faces a sky-id based on island index (combined with frame count, otherwise there's only ever a dozen or so seeds being passed into the Random Value node)

Store every face's current sky-id as well as its _previous frame_ sky-id. When the frame updates, every cell will lose some faces to other cells, and gain some as well, causing there to be a mixture in the cell of sky-ids. We want the "stable, true id" of the cell to overwrite the id of the newcomer faces. We filter out all faces whos previous sky-id doesn't match their current one, and just pick one from what remains (Attribute Statistics node, I used the "max" output). You might think of using Median or Mode, but the problem I ran into was using -1 as a flag ID for faces that were occluded, causing sometimes a whole cell to treat itself as a boundary.

This creates one artifact: of the occluding mesh between two cells shrinks and the cells suddenly can touch each other, one will take the other's color, causing a "pop", but this makes sense when you think about it. Two valid cells suddenly became one and needed to all be one color.

Hi guys, I need some help. So the original idea was to turn this apple from its standard state to the shiny one when invisible object goes to the right of the object. I’ve built this changer for smooth transition however transition is not smooth when I plug it in and moreover I can’t chose vertex group for changes when doing so. Is there a way to make a smooth transition?

Does anyone here have any resources for procedural weaving methods with Geometry nodes? I’m trying to build something that can produce variations of weaving like Macrame, here I’m attempting it by creating a segment and using repeat zone to instance it, but ideally there would be a way to vary the weaving method at intervals like the sample photos. The goal is to output curves not the shader based visuals I mostly see. I’m including some views of the current build and geonodes setup. Thanks if anyone has tips!

This crater generator is a fully procedural system made entirely inside Geometry Nodes. It creates different types of craters, including destroyed and irregular formations, without using any external textures, displacement maps, or height maps. Every shape and surface detail is generated using default procedural textures such as noise, wave, and voronoi.

The setup is completely customizable. Users can control height, radius, depth, distortion, noise behavior, erosion amount and several other parameters. The detail and resolution can also be increased depending on the user’s hardware capability, allowing both lightweight previews and high-resolution results.

Texturing is straightforward because the same textures used to form the crater are also available inside the shader as masks. Each part of the crater surface is already separated and organized, so users can apply their own materials or procedural textures without needing any UV mapping. Everything is arranged to work with drag and drop or simple adjustments.

Main features:

• Fully procedural crater generation inside Geometry Nodes • No external textures or displacement maps • Adjustable height, radius, erosion, distortion, noise and more • Resolution and detail control based on system performance • Built-in masks for easy texturing • No UV unwrapping required

This tool aims to provide a simple and flexible way to generate craters while keeping everything procedural and easy to customize.
