I am a newbie to Geometry Nodes am am trying to scatter some instances on a mesh, but only on the upward facing normals. Is there any way for geometry nodes to do this?

If not, is there any way to only scatter instances on upward-facing faces? That could work for me to.

Here the node Compare helps you.

enter image description here

Set this to Vector, Dot Product and Greater Than or Equal, and use as second vector $(0,0,1)$ (pointing up).

This selects the upward pointing faces, which you can use directly with Distribute Points on Faces.
