Geometry Nodes is a node-based system in Blender for creating and manipulating geometry procedurally. Introduced in version 2.92, it allows for non-destructive modeling and advanced effects by connecting nodes to define workflows. Use this tag for questions about creating, modifying, or troubleshooting setups using Geometry Nodes.

Assign ID to all vertexes of the same instance (geometry nodes)
Essentially I want to distribute instances on points using geometry nodes, then realize instances and transform each one according to their index. Example (all instances with index 1 are tranformed by …

adding geometry with geometry nodes over time e.g. a sphere moving in a circle -> torus
Something like this?
You start by creating a curve around which you build a cylinder and at the end of curve you place a sphere of the same size. If you want a torus just start with a circular curve. …

Sort points by distance from object (expanded: sort any field)
I have two sets of points and I need to connect them with curves using geometry nodes. The problem is the that curves need to connect two points based on their distance from two objects.
Example, a po …

Trying to make spiral staircase using geometry nodes with no luck - Blender 3.1
The idea is to create a one step and then instance it on deformed mesh line.
I recommend you start with one rectangle where you move the object origin to one of the small faces. The create another obj …

Translate objects along curve instances
I have a set of start positions and a set of end positions and I eventually want to connect the two by bezier curve. And then use this bezier curve as a path for a selection of objects. I can get a si …

Sort points by distance from object (expanded: sort any field)
After a few weeks I tried again using a more computer programming approach and figured it out. That being said the solution is fairly complex and future readers should probably just learn how to use …

Find highest index value for each Mesh Island. Is it possible? Geometry Nodes
While blender geometry nodes are probably not Turing complete, most questions should be possible to solve with a computer programming approach. I came up with two solutions (for "messed up" vertices) …

Select a subset of points in geometry nodes?
I have found another solution that is simpler than André Zmuda solution. Though it does still suffer from some statistical approximations like Marty Fouts solution, but the "mistakes" are much less pr …

Can't get the switch node to accept my value input
The switch node can only take a single value as an input, you are trying to pass a field to it. Instead of using a switch node I recommend the following:
Replace both object info nodes with one colle …

How could I get the distance of a point to its nearest point?
It is technicality possible, but I would recommend searching for a different solution. The idea is to create as many copies of an object as the number of points that are in said object (or produced on …

How to change of the color of instances placed around a sphere based on their location
I would like to add to "LuckyOne"s solution. As I see it you want the colors to rotate around the sphere origin. The base idea is still the same, make geometry nodes output some values, that you can t …

How to get location of origin of all objects in selection useing geometry nodes. 3.0
So what I am trying to do is displace an array of points based on location of another object. The nodes work well, when I "call" each object seperatly using "Object info node". But I need to "call" a …

Accumulate Specific editable shapes on Specific points on a mesh line with no gaps
I am not sure what exactly you want but this is the basic idea.
So we start by creating a random field. Then we re-scale one of the values, after that we accumulate field and use it to set origin po …

How to outset faces in geometry nodes
So essentially I need to scale edges so that the offset after transformation is constant distance away from original geometry (something like the opposite of inset). I need it to be procedural, so it …
