Concept Graph is perhaps the single most impressive plugin I have seen yet for the Godot game engine. It aims to bring the world of procedural content generation to the Godot game engine and quite frankly, even in an early experimental state, it succeeds. Even in my short hands-on time with Concept Graph, I can really see how this could be a game changer for many Godot developers.
Described on the Wiki accordingly:
Concept Graph is a free node based content creation tool integrated in the Godot game engine. The node graph is composed of many small independent nodes connected together to create a complex result.
This add-on is still in alpha. It's not considered production ready, but if you want to play around with it, I'd love to hear your feedback on the UI, general usability, features or anything else. If you want to contribute to the code, head oven to the Advanced topics section to get familiar with the code-base architecture.
Quite frankly, Concept graph is really one of those things you should see in action to truly appreciate it. You can check it out in our video below including quick installation and getting started instructions. If it excites you as much as it did me, you can then learn more in this in-depth video tutorial by the addon’s creator @HungryProton.
