One specific Brep does not appear in the ShapeDiver viewer

Grasshopper ShapeDiver
1

Context:

  • The Brep is closed and passes Rhino check (no bad objects).

  • Mesh brep in Grasshopper works correctly (valid mesh output).

  • The problem persists even when the Brep is converted to a mesh and when all data trees are flattened.

  • The Brep was previously involved in conditional logic (Stream Filter), but this has been removed and the geometry rebuilt.

Critical test result:
When I isolate only this single Brep (or its mesh) in a new definition and publish it:

  • ShapeDiver does not show this Brep.

  • Instead, the viewer sometimes shows a different Brep from the project history.

What I have already tried:

  • Explode / Join, rebuild, remesh

  • Remove Stream Filter and conditional logic

  • Flatten / clean data trees

  • Replace Geometry Output component

  • Upload as a new model with new name (not overwrite)

  • Publish only this one object in isolation

None of these resolved the issue.

Could you possibly help me out on this?

Could you share a minimal definition with the problematic brep?

This issue happens because of a breaking change between Service Releases 25 and 27 of Rhino 8.

Our servers are still running SR25 but we will update to SR27 in the next few days, at which point you can upload your model again and the issue should be resolved.

I will write again here when SR27 is deployed.

Hi Mathieu,

Thanks for the verification and update.

I’ll wait for change to be completed and try again.
