Took a break from this project between September 2018 and July 2019; had switched jobs and had to spend time adapting to being a Producer again. However, in mid-August of 2019, Unity released a set of prototyping assets called SNAPS. Was surprised to discover that the height measurement for SNAPS was precisely the one I used, which implied adapting the SNAPS prototyping assets for use in my Procedural City Generator would be doable.
