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.

Rotate instances after being realized
I have a question which is similar to this one
but with a slightly different setup. I'll attach a file to show what my setup looks like.
After I realize the instances I lose that rotation I had applie …

Binding a mesh object to a specific vertex of a curves object
Yes you can! Just select the point you wish then 'Ctrl+select' the mesh object (if you can't do it through viewport, do it through Outliner) and then 'Ctrl+P > Make Vertex Parent'. But why do you say …

Trying to conform indices from two different geos
All right guys, I'll try to simplify a question I brought a few days back.
I'm basically trying to conform the points of some horizontal curves (which are duplicates from an underlying curve) to the p …

Geonodes A way of sampling the indices of the source geo rather than the target geo
Generally speaking, we use the sample index in order for a 'source' geo to adapt to the index logic of another ('target') geo. That I can do well enough already. What I'm not able to do is the opposit …

Is there a way to make the tangents actually follow the last curve segment direction? [duplicate]
The tangents are a little visualy rebel, idk mathematically why, but they form an angle between curve segments. Is there a way for them to actually follow the direction of the last curve segment perfe …

How to make Geonodes understand that an index sequence is a selection?
I've done some fancy math to achieve a specific index sequence and I want Blender to understand that this sequence is a selection of indices. When I input them to a compare node, only the indices that …

Sampled curve only consider one spline (workaround)
I created a grid with an underlying curve and the "poles" are splines instanced on the curve points, poining up, the base curve gets duplicated n times and they are placed along the instanced splines …

Sampled curve only consider one spline (workaround)
Fixed! It was only a question of capturing the index from the original curve.

How can I find the angle between curve segments?
I'm trying to figure out how to do it, I only neeed the angle from the X-Y axis between one segment and the next one. I checked out some other similar questions, but none of the ones I found were abou …

Smarter way of changing Evaluation Domain?
Is there another way of doing this? I want the length of each hair curve per point, but Blender calculates the length of each point based on the previous point rather than based on the length to the r …

Curve normal to follow geometry normal
I wished to know how to make a curve normal follow the normals of a nearby geometry. I saw they have asked that already, but slightly different from what I wish I guess... Because in other cases, the …

How to make the instances scale to follow the base curve tangent?
Oh I get it! What was getting in the way was that 'Curve to Points' node, I just replaced to 'Resample Curve' so I didn't lose the info from the original curve - this somehow was screwing up the tange …

How to make the instances scale to follow the base curve tangent?
So I have this horizontal curve where I'm instancing spirals from. I grab the tangent of the curve and scale the instances oriented from that vector but it doesn't work as expected. How to procede so …

How to make the instances scale to follow the base curve tangent?
The best result I achieved so far has been this one, but as you can see it's still not aligning perfectly to the perpendicular. As you can see, I grabbed the perpendicular of the base curve's tangent, …

Is it possible to make multiple splines to be sampled in a 'sample curve' node?
Summarizing: I have a spline on the ground that is instancing other vertical splines ('poles'), then I'm copying the ground spline and sampling each point to a different pole driven by a factor. This …
