I haven't actually tried it yet. I've been trying to install it locally rather than globally, and failing to get it right. (All of the other plugins I've installed locally work, but the Plugin Manager just lists face tracker as "not found". In the past I've either grabbed a tarball directly, or used "ar -x" to pull stuff out of a .deb. This is on Pop! OS 24.04 BETA running OBS Studio 32.0.0.)
