Questions tagged [geometry-nodes]

Use this tag for questions regarding Geometry Nodes, a modifier added to Blender in version 2.92 to manipulate geometry in a Blender scene.

Geometry Nodes are a node-based system introduced in Blender 2.92 that allows the user to modify the geometry of an object in more complex ways than normal modifiers.

It can be accessed by adding a Geometry Nodes Modifier to an object.

Geometry Nodes have made great strides in development since their introduction, and differ significantly from each other in some Blender versions.

In the post Geometry Nodes Overview you will find an overview of the nodes available in the different Blender versions.

More information can be found in the official Blender Manual.

Can't find the node! Which node is available in which Blender version?

It's not hard to lose track of all the Geometry Nodes in Blender, especially since names and function have changed over time. ...But honestly, it's getting pretty tedious. Many tutorials talk about nodes that I can't find in my version, and the…

How can I re-sort the points/indexes of an object in geometry nodes?

I wonder if there is a possibility to re-sort the indexes of a mesh according to a certain criterion? Again and again in Geometry Nodes unfavorable situations arise where the point distribution or their indexes are in irregular order. For example, I…

How can I bevel the edges of a cube with geometry nodes?

I would like to use Geometry Nodes to add beveled edges to a cube, exactly (!) like the modifier Bevel would do. I am interested in reconstructing the effect as detailed as possible. Any ideas?

Perfect chain generator

So Generate chain using GN is simple, right? Resample curve, instance torus aligned with tangent vector and rotate every odd instance 90deg. So easy. If you have a smooth curve, it looks ok. But things goes uncanny, then curve is... too…

How do you select a single face on a cube in geometry nodes?

This is a very simple question that I cannot seem to find an answer to online. All I want to do is make a selection of a single face in a mesh to apply a material to it. The example image shows a red cube with its GN setup. How do I make that only…

Modify instance geometry based on the location of the instance

I'm trying to use an attribute generated from an instance position to affect the geometry of the instances. For example with the below setup, let's say I want to shift just the 4 top vertices of each cube, along the x-axis, by the amount given by…

How can I get a new random seed for every object using the same geometry nodes?

I'm making a small medieval city using geometry nodes in Blender 2.93, where each building is a separated object, but they all share the same modifier list (and the same geometry nodes). I added some randomness to the height of the buildings by…

Is where a way to pass data to material without realizing instances?

So, I have set up like this (3.1): I generate some color (random is just for example) and send it to output to use it in the material. But the only way to make this work is to use realize instances node. So I want to know if where is a way to do…
