The plugin works fine even if I name my nested folders with a .vst3 extension.
Here is one of the tests I did:
- Copy myplugin.vst3 bundle into the VST3 dir - not detected
- Delete the bundle and create a regular folder named myplugin.vst3 in the VST3 dir, then copy the contents of the original bundle inside - plugin detected.
So it seems like the bundle container on Windows is having issues but I can’t figure out why it’s different than a regular folder.
