I’ve spent many hours trying to solve this issue, so for now, I’ve found a workaround for a large number of Rhino + OneDrive users experiencing the missing thumbnail preview problem. This solution requires additional disk space and installing another program, but it works.
You need to install FreeFileSync (with RealTimeSync) to synchronize local folders.
Here’s how it works:
- Create a new local folder outside of OneDrive.
- Set up synchronization between this new local folder and your OneDrive folder containing your 3D files.
- Forget about the OneDrive folder and work directly in the local folder.
I know this somewhat defeats the purpose of using OneDrive, but for me, the lack of thumbnail previews is a major issue. This way, I can see the previews while still keeping my files synchronized and accessible from another computer if needed.
Hope this helps someone facing the same problem!
