For people making add-ons or patching GTS themselves: Hexanode's guides from the GTS Black Book. For the add-ons themselves, see Add-ons.
- Creating an add-on: Naming, scope, versions, file conflicts, patches and plugins: making a collection that sits on top of GTS.
- Generating files: Grass cache, terrain LOD and object LOD: what order to make them in, and catching a tool's output with MO2.
- Grass cache: Regenerating GTS's grass cache with NGIO, partly or in full, with winter grass.
- Terrain LOD: Making GTS's terrain LOD with xLODGen, with the settings for each LOD level.
- Object LOD: TexGen and DynDOLOD for GTS: the settings, worldspaces and rules.
- Race patches: Custom races with GTS Community Edition and Race Compatibility SKSE, and Hex's patches for five race mods.
- Verified Creations: Bethesda's paid mods with GTS: which work and Hex's patches for them.
- Other patches: Patches that fit nowhere else.
