One of our interns is having a problem with both the menu tree and the 3D preview. The error message reads: “There was an error creating a background preview in Dynamo. This could be due to a lack of graphics resources on your machine. See the log for more information”
She downloaded Dynamo version 2.4 as well as 2.1 and both have the same issues.
We followed all the steps on this page: https://github.com/DynamoDS/Dynamo/wiki/How-to-Utilize-Dynamo-Builds, as well as doing several variations on these instructions (integrated or high-performance), set Dynamo as administrator, checked the video card in the Bios, etc. But all to no avail.
She has DX12 installed as well as several C++ redistributables.
She used to have the other error message as well: “LibraryUI: Could not load file or assembly ‘CefSharp.Core.dll’ or one of its dependencies. The specified module could not be found”, but for some reason this disappeared (but without actually solving the menu tree problem).
She doesn’t have any version of Revit installed. Might that be a problem?
We checked this topic as well, but did not help unfortunately: Revit 2020 Dynamo 2.1.07733 Default Background Preview greyed out
So it seems we hit a dead end. Does anyone have the golden solution to this?
Update 1: She has a brand spanking new Dell precision 5540, so I don’t think hardware is actually the issue.
Update 2: After a restart, the menu tree now does seem to work, so that’s one problem down, but the 3D preview still to go…
Thanks again for the help,
