I started running through these instructions. When going to test them, I ran into issues due to having a newer version of Blender (4.2). The instructions mention it only being tested with 3.0 through 3.3, so an error here probably isn't totally unexpected. It looks like the GeometryNodeTree has changed.

Thanks @jmackay2 . Could you please file a bug in the gz-sim repository with this information?
