One situation that I often encounter while making animations with geometry nodes is the transfer attributes from a point (in a point cloud) into an instance that's created using that point.

A typical scenario:

  • On a base mesh (sometimes with sometimes without PointDistribute) I perform various calculations, so that now each point in the mesh (or point cloud created via PointDistribute) now contain some new attributes, for example phase (0-1) of the animation that I want each particular point to have.
  • I use PointInstance to instantiate an object on that point cloud.
  • I then want to use the "phase" attribute that I created in the point cloud, so that each newly created instance can "inherit" phase attribute from a point that's used to create that instance.

When in 3.00alpha AttributeTransfer node appeared I thought it would perform that function, but it doesn't. Any ideas? Should I explain the question better? Thanks!

    $\begingroup$ Yeah, that's a missing functionality for now I'm afraid. I'm sure it will be added in a future version. AFAIK custom attributes are lost when using the point instance node $\endgroup$

Since 3.0 you can use the Capture Attribute node for this. Here is an example:
