From the creator of Atmos, a plugin developer for multiple years -
This update is meant to be beneficial for plugin developers and professional game studios, not the average joe schmoe. While I do acknowledge that independent creators and even children will not be able to download some gamepasses, I believe that the marketplace will shift into 2 categories, free plugins for beginner developers which are basic in terms of features, and USD plugins for professional and expert developers jam packed with features.
Again, plugin developers have the option to distribute their plugins for free. It’s not like being in an unsupported country is the end of the world, it’s a new feature.
