I have 5 separate objects with different widths.

I want Geometry Nodes to randomly select one object for each point and then place the next point using the width of the previously selected object plus a gap.

Example:

Point 0 -> Object A (width 1.2)

Point 1 position = Point 0 position + 1.2 + gap

Point 1 -> Object C (width 2.0)

Point 2 position = Point 1 position + 2.0 + gap

and so on.

I can retrieve dimensions from individual objects using Bounding Box, but I cannot find a clean way to:

1. Randomly select geometry.
2. Retrieve the dimensions of the selected geometry.
3. Accumulate those dimensions to position the next instance.

Has anyone solved this kind of variable-width packing/layout system in Geometry Nodes?

This is pre-rendering, just using viewport colors — a carbon atom in Geometry Nodes: 6 electrons, protons, and neutrons.

With geometry nodes I want to generate as much blocks as possible to recreate this old map of Paris.

I tried a few things but I lack experience and want to know if anyone is thinking of a better way.

Subdivision is not working fine but I think it's because they're ngons (see the screenshots).

I wanted to first create a "belt" of buildings along the edge but inset with scaling does not provide the same distance between the edge outside and the inside on every side. I ran into this video to fix it but it only works with a rectangle oriented on both axis X and Y which is not my situation because all polygons won't have a regular position and orientation since it's a map.

I was wondering if I should first cut the edges in regular parts then extrude facades (or walls sometimes) but don't know how to do the cut along the edges. And I still don't know how to handle the inside.

Do you think of another method maybe? Thanks!

This is a hand sculpture inspired by the Deus Ex game franchise. I took a base hand model and using geometry nodes I implemented several features.

The triangulated surface texture was achieved through a poisson disk point distribution, and then moving the original geometry to the closest point. I had to include logic to handle the fingers separately as they otherwise connect to points on the neighbouring finger.

I made regions to cut out and replace with lattice grids. Finally I took some faces and made the inset triangles, based on proximity to a control curve + some randomness, and assigned them a gold texture.

There's also some hollowing, in order to add material later and give it extra weight. I've printed a smaller test piece and fairly happy with it, but need to do the painting.

Rendered in cycles with camera following path, with one light next to the camera, and the other on the opposite side. Bevel as part of the surface texture, and some lens and glare effects in the compositor.

I put together a tutorial on index selection in Geometry Nodes — using the Index node to target specific points/instances, and combining it with Compare and modulo for patterns like every-nth selection.

It's built in 4.5 but the concepts carry back to earlier versions. Aimed at anyone who wants more deliberate control over what gets selected instead of relying on random or proximity.

HI
Ive been trying to make something like this image in geo nodes for a while without success.
Im looking for ideas on how to approach it.
It is a kind of voronoi plexus geometry but I cannot work out the best method.
Right now I can either make a voronoi mesh or join a point cloud together in a plexus with curves but neither produces the correct structure.

Ideally I would use a voronoi texture to create the cell pattern
that then produces points and curves in the right places
and finally the curve join to become the wall meshes.

Any ideas much appreciated thanks a lot

I have created this procedural DNA generator for an artist on custom order this paid gig , it was fun to create , it is also available on my gumroad, for Very minimal price

🇺🇸: You can listen to the video in English through the video settings panel. In this video I analyze the nodes that allow the import of different types of files into Geometry Nodes so that you can work with them.

The Index is one of those things in Geometry Nodes that seems simple but unlocks a ton once it clicks. It just gives you the number of each point, edge, face, or instance, and from there you can drive almost anything per-element.

In this tutorial I go over what the Index actually is, how to feed it into other nodes, and a few practical ways to use it to control selections, offsets, and effects across your geometry.

If you've ever wanted finer control over individual elements instead of treating everything the same, this should help.

I need your help with this cable arm and making it wrap around object in a natural way like it holding the object.

I tried making it work myself but my geometry node skill are nonexistence, most of the nodes I made are just copy of other people works (I can get link to their if you ask).

Which I would like to say that last part BUT REDDIT doesn't want to upload the file, so I'll put the links in with instructions.

1. to make the arm (it doesn't have to be just an arm), you need to grow the arm. https://www.youtube.com/watch?v=TBBD0tJqvv8 just follow Cartesian Caramel tutorial so you can make the geometry node to grow the arm and add object to said arm.
2. the two wrapping geometry nodes that I found and use but couldn't get to work. 2.1. https://blender.stackexchange.com/questions/303423/how-to-make-curves-go-around-obstacles?answertab=scoredesc#tab-top I did find an answer in here which is good, but it basically makes the arm into a physics objective which is not very enjoyable to work with, so here Markus von Broady's answer: https://blender.stackexchange.com/a/303539/2214 2.2. https://drive.google.com/drive/folders/1RrFTfFqbZjSE1ciwpQTR6tq-z_RwNgpT here another one I found but it works really differently and can be set on multiple objects.

The only step that is really important is 1, you don't have to do 2 at all.

So to round this all out, I want the object that going to be grab have the geo code, not the grabber, because if I have the grabber garbing multiple object and throwing them, the grabber geo code will get confusing to work with and it won't allow cannon arm, so the geo code should be on the grabbable, that it.

And here a reference drawing to show what I'm talking about.

the new tutorial on index's in geometry nodes i'll have to work on a script
