Hi,
there’s partial support in the latest release. It’s working for macOS, Linux and the latest Windows 10 version, Windows 7 is not supported. For Windows, you need to use at least the Windows 10 Creator Update SDK for compilation.
After that, you just need to place your fonts into a subfolder named “Fonts” inside your Resource directory (so you need to use the package structure for your plug-in). And then you can use these fonts by name in VSTGUI.
Cheers,
Arne
