Impossibile caricare il contenuto di rendering dal file

/Users/matteo/Library/Application Support/McNeel/Rhinoceros/6.0/Render Content/Anteprima contenuti/AnteprimaStudio.renv

Causa: Bad File
The file could not be read or was not Unicode /Users/matteo/Library/Application Support/McNeel/Rhinoceros/6.0/Render Content/Anteprima contenuti/AnteprimaStudio.renv

I also have this problem since I installed the Rhinoceros 6 for Mac. Is there someone who can help us?

Thank you very much!

Thank you for reporting this.

Can you please run the _SystemInfo command and paste the results back in here?

I’m unable to reproduce this issue in 6.19.19298.01152 running in Italian and French.

In earlier versions of Rhino 6 for Mac, we had bugs of this sort but we fixed the problematic render content files that were causing this. However, when Rhino for Mac unpacks Render Content to ~/Library/Application Support/McNeel/Rhinoceros/6.0/Render Content/, we NEVER delete or overwrite content that is already there.

Here is what I would suggest:

If you have never edited the default Render Content found in ~/Library/Application Support/McNeel/Rhinoceros/6.0/Render Content/, I would:

  1. In Rhinoceros > Preferences > Languages make sure your desired language is properly set.
  2. Quit Rhino 6 for Mac completely.
  3. Use Finder to navigate to ~/Library/Application Support/McNeel/Rhinoceros/6.0.
  4. Drag the Render Content folder to your desktop to move it there.
  5. Launch Rhino for Mac. The default Render Content should be restored (with updated files). The bug ought to be fixed.

If you HAVE edited the default Render Contents

  1. Follow steps 1-3 above.
  2. Do NOT move Render Contents, but rather find the offending files (such as Anteprima contenuti/AnteprimaStudio.renv in Italian) and just delete those files.
  3. Launch Rhino for Mac. The default Render Content should be restored (with updated files). The bug ought to be fixed.

Any better?

Hi @ledouxpa-

If you switch to the latest Release Candidate, are you still experiencing this bug?

-Dan

Hi Mister Belcher,

Thank you very much for all your advices. I first switched to the latest Release Candidate (6.20.19310.02452, 2019-11-06) but the problem is still there in the french language. I tried setting Rhino in english language and the problem is not occuring in that case.
So I tried your first advices but I am unable to find the Render Content folder with the path you gave me. I can only find a License Manager folder inside the folder 6.0. Please see the print screen attached. So if you know where and how I could find it, I would like to try this solution.

Thank you again

Hi @ledouxpa-

We have a better idea of what is going on now and we’re working on a fix:

RH-55601 Various default Render Content cannot be loaded or is corrupt

I doubt my previous suggestion would help, so I don’t think you should try it unless you’ve never edited the Render Content.


What you are looking at in the above screen-shot is the “global” library: /Library/, not “your” library: /Users/[yourname]/Library/. This is a common mistake that I continue to make after years and years and years working macOS.

The Render Content is in “your” Library, specifically in:
/Users/[yourname]/Library/Application Support/McNeel/Rhinoceros/6.0/Render Content.

(On macOS, ~ is a shortcut for /Users/[yourname]/)

Dear Mister Belcher,

Thank you again for your help. OK I understand where to find the right library.
So you advise me to follow the procedure RH-55601
in order to solve the problem or I should wait a future solution that you are working on?

Thank you

We are working on a fix, but it could be a few weeks until the first Release Candidate appears where it will be testable.

It looks like files with accent characters like Ä,Ö,ü are the issue. Until we figure this out and publish a fix, renaming those files will likely fix the issue.

Ok, thank you very much for your precious help.
