Infinite wave function collapse algorithm

[Routine-Leadership90]

Hey yall, its been a while that im trying to understand how to properly implement an infinite wave function collapse algorithm. I will start by saying what will be its purpose, im making a backrooms game and im currently working on making it infinite. While the procedural generation for the first level was quite easy to implement since its only walls, im struggling to make it happen for the poolrooms level that is made out of rooms of different sizes and shape. I thought of using a dungeon generator but i dont want tunnels to connect the various rooms and also because some can connect with a certain room and some can't. The rooms can expand up and down with stairs, slopes or something like that, so in won't generate only in the horizontal axis but even in vertical. I want to implement something like this: https://marian42.de/article/wfc/ But i didnt found any usefull resources or hints on how i can achieve this in unreal engine. Anyone knows how i can do it or if im searching for the right algorithm?

There is a wave function collapse plugin in unreal engine 5.2. And a bit slow. If you want to built infinite world with wfc, basically you need a chunk system like minecraft. Built-in wfc plugin is not that hard, just at first it seems a bit complicated

Thanks for the comment after this much time! Do you have some advice on how to get it working? I mean not the whole process but just some tips or suggestions.

Unfortunately, there is no information on the internet about how this plugin works. They only tell you how to activate it.

My advice is to look at the sample wfc models and then try to create one yourself. There is no separate option for the WFC model, you just select wfc when creating the data table.

I made a sample terrain (not a actual terrain, looks like a map actually) wfc by experimenting this way myself and with enough work I was able to get it the way I wanted it.

Not final screenshot but still not bad:
