How to delete an island whose min x less than -1

First I plug a Position node into a Vector Math node set to Absolute, this way all position values will be positive, i.e. if you want to check if values are below -1 or above +1, you can use a Compare ...

How to delete an island whose min x less than -1

You can avoid a repeat zone which will be a life-saver if you have thousands or more of mesh islands, if you use the below trick: move each point satisfying a criterion for deletion to the coordinate ...

How can I merge overlapping faces converted from a text string in geometry nodes, to avoid Z-fighting issues during rendering?

In Blender and a lot of other software, curve filling works by filling the space that is wrapped by an odd number of curves. This is why you get undesired holes, but this is also why you get desired ...

Geometry nodes: random value as single value rather than field

Nodes are smart enough to know if their result is based on a field, and therefore they should return a field (exceptions are Sample Index and Attribute Statistic, which use a field to get a single ...

How do I maintain Bezier circle resolution when selecting fill mode "none" for processing with Geometry Nodes?

I honestly can't understand what exactly you're trying to do here (it may be an XY problem), but your question about why Fillet Curve works so strangely here is ...

How can I merge overlapping faces converted from a text string in geometry nodes, to avoid Z-fighting issues during rendering?

I suggest the following: Move the points of the curves along their normals by a small amount (e.g. $0.00001$). Fill the resulting curves with Fill Curve. Do the ...

How to delete an island whose min x less than -1

Here is the example how to remove all islands that Z is less then 0: Basically, it loops through all islands and collect it if minimum of Z positions is grater than 0.

Summing volumes of nearby objects in geo nodes

This solution groups the datapoints together using a grid with cell size depending on the distance to camera. In order to be able to animate and make transitions smooth, the grid is dynamically ...

Geometry nodes - Pack UV Mesh quads sliced by Grid into first UDIM (0..1)

You're 2D-arraying a default "Grid" and then sample UVs from it, however when you're sampling at a position equal to an edge/corner of the source "Grid" array, there's 2/4 ...

How can I best join more than two curves in Geometry Nodes?

It all depends on what kind of effect you want to achieve. A curve is defined by an array of points, so you can just glue multiple arrays together and reinterpret as curves: Of course the points can ...

How to add Fall-Off texture to every instance in geometry nodes individually and keep each instances color?

Thanks to @Jakemoyo I was able to generate the shader I needed! I had to use an object from the scene, the white circle, that I UV unwrapped and added a mix shader with a principled and a transparent ...
