I see this is all committed to master branch. However, I'm unable to build it myself on my M1 system. I'm simply following the "Building Blender for macOS" instructions. Am I missing something?

Today I decided to completely delete the Blender repository and related stuff (the Blender-git folder) and do a fresh checkout and build of the source code. To my surprise I again stumbled upon the fact that the build failed, because the darwin_arm64 libraries weren't downloaded. I decided to look into the matter and it turned out that my system somehow has both an Intel and an ARM version of Python3 installed. And the Blender make update target used the Intel version. So the call to platform.machine() returned x86_64, which caused the wrong libs to get downloaded.

Leon Zandman (lzandman) added a comment to T81257: Initial version of USD Importer.

Another issue is that some of Apple's USDs contain textures in HEIC format (like this iMac USD). This format currently isn't supported by Blender, so they will fail to load. I've converted them to JPG, which fixed the Material Preview. But still the render preview is black.

However, there is an experimental feature for converting USD Preview Surface shaders to Blender Principled BSDF node networks. This can be enabled by checking the 'Import USD Preview' option in the 'Experimental' section at the bottom of the USD import dialog.

However, I haven't noticed missing materials. (I believe all the materials in the AirTag example imported for me.) Do you have an example where some materials didn't import?

I just imported the AirTag file on a build that includes your latest changes. The file dialog bug has indeed been fixed.

Another issue I noticed: when I select an USD file in the USD import file dialog the background of the filename input box turns red. This normally only happens when you try to save/overwrite an existing file. But since I'm only importing the file I don't think it should turn red.

I love this gets added to Blender! I just tested the "usd-importer-T81257-merge" branch on a couple of USDs of Apple products I downloaded from Apple's website (like this AirTag). In fact they are USDZ files. I noticed these aren't supported. Are there any plans to support USDZ files?

I got a different error after updating Xcode. Can't quite remember, but it was something like "unable to find sdk 'macosx11.1'". I did a make update from the Blende repo. That didn't help. I then tried to recreate the Xcode project by doing cmake . -B ../build_xcode/ -G "Xcode", but that also threw an error. After some Googling I found that I needed to re-install the Xcode Command Line Tools. But that also didn't help. Finally, I created the first symlink from this article and I was able to build again: https://developer.apple.com/forums/thread/667561

Actually you reported multiple issues on both MacOS and Windows. I'm making notes and will probably make changes for the Windows platform. Someone else will have to address the MacOS-related issues.

Unfortunately, I think this thread has gotten a bit off track by all the responses about thumbnail generation. This issue isn't related to thumbnail generation. Yes, when Blender generates thumbnails it will trigger the download of those cloud files. However, this I could see as perfectly acceptable behavior, because Blender actually has to read the file for thumbnails to be generated.

The central problems seems to be that users are asking for thumbnail creation for files that are not fully downloaded. So if this issue is fixed we'll get complaints that users cannot see thumbnails for files in OneDrive. LOL

I was just experimenting with these OneDrive pinning attributes on my local machine. They've changed the implementation a couple of times during these last years, but I think the current Windows 10 implementation is pretty stable.

Why does the Blender file dialog even need to know whether a file is readable or writable when enumerating them? Is this info actively used at that stage? Or is it gathering this info so add-ons can use it?

Other calls to this function should not be affected, this is purely about requirements to run OpenImageDenoise.

Why did you add this Apple exclusion code here, @Brecht Van Lommel (brecht) ? I think it should be inside the function BLI_cpu_support_sse41() in source/blender/blenlib/intern/system.c. That way other calls to BLI_cpu_support_sse41() will also benefit.

After some more spelunking it appears that the download is triggered specifically for NSURLIsReadableKey and NSURLIsReadableKey. Checking for the other two keys won't trigger a download.

It's also possible that GIT/SVN isn't picking up that you're on a M1 Mac and thus isn't downloading it. In which case that will need to be fixed by the dependency maintainers. But in the meantime this may help?

  1. Open a terminal and change your directory to /Users/YOUR_NAME/Blender-git/lib/
  2. Run the command svn checkout https://svn.blender.org/svnroot/bf-blender/trunk/lib/darwin_arm64/
  3. Change the terminal back to /Users/YOUR_NAME/Blender-git/blender/ and run then run the make update and make commands.

Thanks! The SVN checkout of the darwin_arm64 repo worked and I now have a working build!

I noticed this too. Your screenshot shows your loading files from a OneDrive folder, so I think this issue is related to the OneDrive Files On-Demand bug that I reported: T87621: The Blender File Open dialog triggers OneDrive Files On-Demand downloads

Is it true that the Intel denoiser is still unavailable? The node says "Disabled, CPU with SSE4.1 is required."
