@SimGuruModSquad What Files Make Up The Sims 4 Worlds?

Thanks!

I managed to get preview the files by exporting them, but all I got is images like this:



There were also a small few that appeared completely blank.

I'm a bit confused about how those files work. :( What I'm looking to do for now is just a plain replacement of ground textures. I also noticed that none of the images contain parts that look like the road textures, which leads me to believe there are other files.
