Hi, thanks for the report. I can reproduce only if the object is created from geometry nodes.

I guess this is similar to #92948 (geo nodes breaks auto smooth and weighted normal modifier.)

There is a workaround for this. You just need to join the original geometry (from the group input node) with the procedural geometry using a join geometry node. Make sure the original geometry is the top-most input on the join geometry node otherwise this will not work.

This workaround also helps with getting vertex groups on procedural geometry, which can be used in other modifiers.

Thanks for the report. This isn't exactly a bug though. The properties in the mesh tab of the property editor are adjusting the object's original mesh-- the one you see when you go into edit mode.
When you create entirely new geometry in geometry nodes, it doesn't have the information from the original mesh, because it's entirely new, just like creating a new mesh object.

In the future we will most likely get some way to get auto smooth functionality working in geometry nodes, but for now this is working as expected, just that the features are lacking.

It might be nice if the existing property panel settings worked on the evaluated mesh (with modifiers). I think this is how it works for all other modifier.

It only appears to work that way for other modifiers because they don't create new geometry, only change existing meshes.

What you suggest might work, but it would also invalidate changes that happened procedurally in the node tree, so it's not quite that simple.

yes, I think the properties panel should only modify attributes for individual elements that haven't had the value set by the node tree. i.e. if the value isn't the default, then leave it alone, otherwise, have at it.
