Rhino command windows not appearing when GH is loaded with complex definition

Rhino Rhino for Windows
1

Hi all,

Has anyone else had this strange behavior of Rhino commands that require window input ceasing to function properly when Grasshopper is loaded (particularly with a large/complex definition)? One of my users is experiencing this problem regularly. Rhino command line commands (like ViewCaptureToFile or Text) work well when Grasshopper is not loaded, but after a large definition with a high amount of complexity (26k components with a lot of listeners), those commands stop generating their WPF windows for user input. Disabling the GH canvas does nothing to resolve the issue, Rhino must be quit and reloaded to begin functioning properly again.

This one has been tough to debug as it only happens on one user’s machine and we have a lot of moving parts (dependency management, custom data schemas, Rhino event listening, Rhino layer management from GH, etc). Just looking for any ideas on where to start looking in case anyone else has experienced this kind of problem.

Thanks!

Marc

Hi Marc - can you run the SystemInfo command in Rhino on that machine and paste the results here?

Hi Marc - a shot in the dark, but do the other machines that do not show the problem also run VRay?

Pretty much all of our machines have Vray for Rhino 6 installed but not all exhibit the problem…
