It is surely procedural, maybe wave function collapse? I’d love to read a writeup from the author, in the same style of Factorio’s

I can't remember where exactly but I think I did read somewhere it was based on wave function collapse.

I think wave function collapse is still super underexplored in game dev. This recent paper is pretty interesting: https://dl.acm.org/doi/10.1145/3582437.3587209

The texture is certainly procedural for brick patterns, etc. but I'll bet smoothing intersecting polys happens at render time.
