Awesome news, Jeff, and thanks for your kindness in doing this. I think given the way T3D works currently - i.e. not incredibly friendly to plugins - it might be the simplest route to simply upload the entirety of T3D with AFX integrated As much as I dislike this approach, the alternative would be to also provide detailed install instructions and a partial repo.
Are the changes to T3D.inc necessary, or would they be accomplished by providing a new AFX module that could be enabled/disabled in the Project Manager? Similarly, are the engine changes specific to AFX, or could they be implemented in the core engine? We've already merged in some bugfixes you had for us.
