Custom materials in Rhino not showing in Enscape materials editor.

I have just spent 6 hours on ChatGPT (for my sins) trying to resolve this issue.

Does anyone else know of an issue with OneDrive or any other possible causes?

Thanks!

Here’s a reply I wrote to another OneDrive question, your problem maybe the same:

Well as a start, you shall not rely on ChatGPT to solve problem. Check the documentation and if nothing related can be found get in touch with support team.
