I’m using these Orchid nodes for Materials drop-down selection. ![image](https://europe1.discourse-cdn.com/flex017/uploads/orkestraonline/original/1X/f1ab9984e1d0f9dde427135d1e0ff2e5e743a26b.png) and they display correctly with the Orkestra input form preview ![image](https://europe1.discourse-cdn.com/flex017/uploads/orkestraonline/original/1X/56c5f3c450f789afabfabebcaf446fb882b5123b.png) but the script doesn’t generate a UI pane when i run from Revit using the Orkestra Addin. Thoughts? ---

Hi there @mclough ! ~~You mean the watch node you set as Output ?~~ Oh I think I just understood! You mean that the UI doesn’t get generated at all when running from Orkestra without opening Dynamo right ? ---

correct. The script is noted as run (with warning), but doesn’t prompt the UI as though no nodes are marked as Inputs. ---

Understood. Can you please try the following : - open dynamo (with orchid loaded) - close dynamo and retry running the script throigh Orkestra If this works , then it most likely has something to do with the fact that Orchid uses a dynamo viewextention to load some of it’s resources. ---

yeah, if i try to access the script through orkestra after opening it in dynamo the UI displays as expected. ---

Alright then I’m 99% sure it’s the view extension thing… we recently had something similar reported. I don’t think Orchid is open source so unfortunately we won’t be able to figure what the view extension does… now this doesn’t exactly answer your question, but I think it’ll adress your issue since you’re just displaying two drop downs and then sending that to a python node. I think OkPy might be a nice alternative 😄! + it will load and run much faster ! I just published a materials input through the OkPy Online Custom inputs browser if you’re interested 😁 ![Snag_1c3db58a](https://europe1.discourse-cdn.com/flex017/uploads/orkestraonline/original/1X/781c66cd556439ca59a6c7217eb992d36ec09138.png) ![Snag_1c3dccfa](https://europe1.discourse-cdn.com/flex017/uploads/orkestraonline/original/1X/babb0ef76d1b63015698371e5d1f2eb7b9b4a907.png)
