Kammerbild shows how to create buildings with nodes and fields in Blender.

Things change fast between Blender builds, and this is especially true for Geometry Nodes. You might have seen Kammerbild creating buildings with a node-based set up a little while ago. 

A lot has changed, so that tutorial gets an update. The new version uses fields and updates some of the setups to work with the latest version of Blender. Indeed, the addition of Feilds in Geometry Nodes makes a massive difference in the process.
