@SimGuruModSquad/@SimGuruEugi: Binary Information for World-Related Files Needed

I'm trying to make a world editor for The Sims 4. It will be an interface where you can open a .world file and drag and drop objects represented by thumbnails, move lots around, raise and lower terrain (this will probably be done by loading heightmaps, but that plan isn't locked yet), change the way the terrain is painted and adjust the lighting. So far, the UI of the program is coming along well, but to get into the actual world editing, I'll need information (as well as to know what the type instances actually are for the ones I don't already know) for the following types, and perhaps even .bt files though I understand if that would be bothersome considering the number of files:

• The file(s) that control the objects in public spaces.
  
• The file that controls the height and depth of the terrain.
  
• The file that controls the textures (I know this is resource type 0x9063660D).
  
• The file that controls the zone lighting (I know this is resource type 0x19301120).
  
• The file that controls the roads.
  
• The file that controls the camera settings for the world (where the camera can navigate to, and where Sims can route to).
  

This would mean a lot to anyone interested in world modding! Even if I'm not successful in completing this project myself, I'm sure it will be equally useful to the next person who takes it up.
