Hi,
I use Blender 2.93 on openSUSE Linux.

I could not get geometry node to create clumps of cubes with cloud texture.
I change the cloud size to 0.01 and 2, but show no difference.

I make sure to boost contrast to 3.

Cloud size 0.01.

I figured it out.
I need to subdivide the plane, until I get to the resolution that I want for cloud texture I want.

Yes, because the “cloud-tex” data is saved per vertex, so the resolution depends on the geometry
