Pursuant to your suggestion, I tried just lifting the lanterns all up, using a translate instances node, then I tried just raising the point light inside and neither of those got them to glow at the top like the original.
When I use ALT-D the lantern and light are the same as the original so I guess I’ll have to do that. It’s just more tedious. Somehow I thought that was basically what the instancing inside of Geometry Nodes did.
