cache folders don't get populated with data during runtime with osgEarth 3.1+

[keince]

I'm currently using osgEarth 3.1.0 build 111 on Windows 10 x64.

Using a simple earth file, I can't get the cache file system to populate the subfolders during runtime.

Here is the output with OSGEARTH_NOTIFY_LEVEL=DEBUG set. I have put in bold the output that I think is problematic. Not sure if it has anything to do on why cache folders are not being populated...

I'm using the command...

osgearth_viewer --window 100 100 1280 1024 test.earth

The cache subfolders get created at runtime but they remain empty during execution.

I posted this problem on the forum but didn't get any response so I'm posting it here as an issue on GitHub.

Here is the earth file I'm using...

I believe this was a defect that was fixed in 3.2. Can you please try it and let us know?
