@SimGuruModSquad What Files Make Up The Sims 4 Worlds?

Thanks!! That will be really helpful! :D
I'm still confused about the regular ground textures though. I tried scrounging through FullBuild6 to find textures and found a few world textures. I applied a random recolour as a test, and it worked, so I know that at least part of the world is controlled by regular DDS textures instead of the ones found in the .world files.
