  • Use Unity Explorer to Instatiate a duplicate of any Primitive Object.
  • After creating it, Type in the Parent Box "StoreHere" (DON'T remove the Primitive GameObject type in the Name, but you can add text after) (Primitive Types are: Capsule, Cube, Cylinder, Plane, Quad, Sphere)
  • You can mess with Position, Rotation, Scale, and [Mesh]Renderer.material.color.
  • Invisible, Wall, Environment, and Visual Key Words available within Naming. Invisible will remove MeshRenderer. Wall will add a Box Collider. Environment will set layer to Environment. Visual will set layer to Default
  • After Map is Created, Hit "P" Key, this will save the data to 2 Files (Located at Folder "RUMBLE\UserData\MapCreator" in Files "Map.txt" and "CustomMap.txt").
  • To Reload your map to Continue Editing, Hit "=" Key to load from File.
  • Map.txt is what UlvakSkillz can use to Hard Code in the Map. CustomMap.txt is what you can use to Load in with CustomMultiplayerMaps Mod.
  • Rename UserData/MapCreator/CustomMap.txt and Copy it to UserData/CustomMultiplayerMaps/Maps Folder.
  • To Load in your Map, Be Host in a Match and both Players need Custom Maps Enabled and you need the Custom Map File Name set to the File Name (Found in ModUI F10 Menu).

IMPORTANT:

  • Don't have any Platform too thick! Things will spawn under the map. (Thin Cubes work Best as Quads and Planes can have Funky Spawning)
  • Don't have Ceilings too Low otherwise Structures will Spawn on the Top Platform.
  • Center the Map around (0, 0, 0) and Players Spawn at (0, 0, -4)[Client] and (0, 0, 4)[Host] getting off the spawn pads.
  • Players dies falling below -5(feet) and above 15(head).

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
