My project file is not that big and I have about 60-80 GB's left of space on my Windows desktop so I don't think that's the problem. My Revit file also says 'Not Responding' while it is making the update but then will make the update regardless in about 5 minutes. To save time and ensure all elements are visible in Enscape, consider creating a dedicated 3D view in Revit, from which to start Enscape. When I hit Resume Update a black box appears instead of the window that say 5% complete or how much complete the Enscape update is. I can use Enscape and Revit but to wait 5 minutes between everychange I make is a problem. My Windows is totally up to date and so is my Mac software. If the objects you are rendering are very complex, Rhino may be slow to shade or. I have tried redownloading Enscape and that did not work. Materials are one of the more complicated data types in Revit. I cannot work on a project like this because I need to see the updates as I work on the project in order to make decisions. I tried changing things as simple as the wall paint color and it still takes forever to make the update in Enscape. For whatever reasons when I make chances in Revit and hit 'Resume Update' in Enscape, it takes 2-5 minutes to make the change- no matter how big or small the change is.

I use Bootcamp on my Mac Laptop and typically have bene fine. I am using Revit version 2020 with Enscape version 2019 and I haven't had an issue until today.
