We recently concluded the miWFC project, in which we investigated interactive methods that offer a designer-friendly, mixed-initiative novel approach to the popular WaveFunctionCollapse PCG algorithm.
The project results were very positively received, and we thank everyone who volunteered to test and give us feedback on various features of the miWFC prototype. Now we're paying that forward, by making the system freely available for the whole community: you can download the latest prototype (for both Windows and OSX) and find the complete code base on this repository.
Feel free to use the system for creating your own content, or to further develop it, under the usual MIT licence.
We hope you find it useful, and can't wait to see what you'll come up with!
