QuickLook fails

[bfree-github]

On Catalina, using either brew or manual install, GLTFQuickLook.qlgenerator is not listed as an installed QuickLook extension, nor does it provide a QuickLook view in Finder for glTF files.

After some digging, I found that Catalina disables the GLTFQuickLook extension.

First, ensure that the plugin is in the right folder - either /Library/QuickLook (global) or ~/Library/QuickLook (personal).

Next delete ~/Library/Preferences/com.apple.QuickLookDaemon.plist

Then go to Settings > Security & Privacy > General and allow the GLTFQuickLook extension to run.

Then Force Quit (restart) Finder. You may have to do this a few times, or reboot.

After all that, I was able to get GLTFQuickLook to display Finder thumbnails.
