Godot Substance Painter Live Link
Similar implementation for the open source game engine 'Godot' (Quickly picking up traction this year) as there is for Unity, UE4 and such.
Thanks to the MIT License Godot is under there would be no such license issues as with copy-left licensed opensource projects (such as B3d)

Live Link to Painter would be great for hero asset/character work.
