Geometry nodes suggestion for a ringworld/ring habitat?

I want to recreate a low poly version of a ring habitat like this and I was hoping for some suggestions as for workflow and how to deform everything to fit the ring.

I suppose I can instance on point and make them face the normals for procedural objects like trees but what should I do for custom designed assets?

I’m thinking of building it flat and wrapping everything around…

After distributing some collection onto some point on some geometry (ring, halo, babylon station, whatever) you have to align it according to the normal.. like so:

Align instances to normals

Ok ! That’s why I asked what version you were using before 4.0… But it’s not that important… So, to fix the nodegraph you should use the Normal output from the distribute point on face, rather than using the normal node. Since the distribute point take a mesh and output a point cloud, there isn’t any normal information , since they are just unconnected points in space. But the distribute point store the mesh normal on the pointcloud for convenience, if that makes sense… You can also try to …

or so..

You can chain Aligns: [image] .e.g. here the x will be aligned in the up direction when aligned around the local z. Good luck.
