The Perovskite Builder - Geometry Nodes
This geometry node network generates perovskite lattices and can be adapted for cubic lattices and unit cells. There is an accompanying walkthrough on the CGFigures YouTube channel for those looking for more detail. There are now two files. The more recent versions include the ability to add internal bonds between the central atom and all the octahedral points with controls for splitting the bond colours. For some reason there was a switch between Blender 3.1 and 3.2 so be sure to download the appropriate version. I'll continue to update as needed.
