If you are working with #GeometryNodes in #Blender you may be as excited as me about the new Self Object node which allows you to easily query the transform of the object that owns each the node graph. The docs mention that you can't obtain the geometry output from the Object Info node downstream of Self Object. IOW, image #1 is an error.

They don't tell you what to do about it. The answer is to use the Vector outputs from Object Info but get the Geometry from the Group Input, as shown in image #2.

This little example graph uses a Grid to create a 2D array of instances of its input stepping the rotation of each instance based on the index of the grid vertices. It's probably not all that useful as-is but shows the sort of thing the new node makes it easy to do.

Feeding a scaled-flat and manually (and randomly) tilted single cube mesh as input, the graph makes something like image #3.
