A lot of professional-grade #GameDev tools for Linux are kind of in this weird half-implemented state, where some version of the software *kind of* exists, but there's a lot of hoops to jump through.
I've been playing with the MetaHuman Creator plugin that exists in the native Linux builds of Unreal Engine for funsies. The plugin itself actually works pretty decently, but editor support for Wayland is kind of half-broken, with menus and popups working in some very weird ways.
After doing some research on supplemental tools, like Marvelous Designer, it seems that a Linux version actually exists, but only exists for an Enterprise-Grade plan at an eye-watering $2,000 per year.
