Field notes

  1. v1.0.1

    Latest

    Code cleanup and performance improvements
    Cached the main terrain collider after the first lookup instead of repeatedly searching for the terrain object during normal update/aiming behavior.
    Reset the cached terrain reference when the active world/save state is cleared, preventing stale terrain references between sessions.
    Replaced unnecessary reflection for standard Unity TerrainData properties with direct property access.
    Updated brush preview logic to use direct TerrainData access for alphamap dimensions, terrain size, and height sampling.
    Updated aiming and painting coordinate calculations to use direct TerrainData properties.
    Replaced reflected GetInterpolatedHeight calls with direct TerrainData.GetInterpolatedHeight(...) calls.
    Updated pending save replay logic to use the cached terrain lookup path.
    Kept the lower-level alphamap mutation and restore logic unchanged where IL2CPP-specific handling is still needed.

  1. Install RedLoader

  3. Extract the ZIP into the Mods folder

    On your PC, extract it into the game’s Mods folder:

    Steam/steamapps/common/Sons Of The Forest/Mods

    Keep the folder structure of the ZIP. Don’t put the ZIP itself in the folder.

  4. Launch the game

    RedLoader loads the mod on start. Press F1 in the main menu to see the list of mods.

Prefer one click? RedManager installs and updates mods and their dependencies for you.
