Forge Installation Instructions Edit

Forge 1.10.2 / 1.12.2 (Single Player) Edit

  1. Download and install the latest recommended for forge 1.10.2 / 1.11.2
  2. Run Minecraft once to create the /mods folder.
  3. Download the OpenTerrainGenerator.jar put it in the .minecraft/mods folder.
  4. Install a world preset

Note: OTG usually requires 2gb+ memory to be assigned to Minecraft (depending on world preset). If you experience long/never ending world loading times, increase memory allocation.

Forge 1.10.2 / 1.11.2 (Server) Edit

  1. Ensure Forge is installed on the server and that Open Terrain Generator's .jar file is in the mods folder.
  2. Install a world preset
  3. Go to the file and set level-type to OTG and ensure level-name is set to your world pack name.

If you have already generated any chunks with vanilla or other world settings, delete the level.dat and region files of your main world to get one with the correct level type.

Spigot Installation Instructions Edit

Tutorial for setting up a Spigot server are here.

  1. Set up the server in the normal way.
  2. Download and put the Open Terrain Generator .jar into the server's plugins folder.
  3. Run the server once to create the /plugins/OpenTerrainGenerator folder (delete the world afterwards).
  4. Install a world preset

Spigot console command permissions

The following console commands can be be used with permissions.yml:









Other Tips Edit

  • OTG doesn't require your players to have the singleplayer (forge) version installed (meaning vanilla clients can connect), but they will get some more features if they have it.
  • Both servers and clients running OTG will require more memory than vanilla Minecraft. If you are experiencing long/endless world loading times or other performance issues it is recommended you increase Minecraft's allocated memory to 2gb+

Versions & Platforms Edit

OTG is currently available for Forge or Spigot for Minecraft 1.10.2 and 1.11.2 only. Also works with Spigot 1.12.2.

Mod Compatibility Edit

Open Terrain Generator works well alongside most other mods and has Forge Biome Dictionary integration to help with modded resource placement, as well as mob spawning rule inheritance to allow biome creators to apply automatic compatibility with mods which spawn mobs on a per biome basis. There are some exceptions, of course. Below are a list of mods that are known to cause incompatibilities or other problems:

  • Mods that change terrain generation like Realistic Terrain Generation/Alternate Terrain Generation/Biomes O` Plenty will either not work or crash.
  • MoCreatures 'CustomMobSpawner' conflicts with OTG's mob spawning mechanics (use MoCreatures without it until this can be solved).
  • NetherPortalFix causes a crash on teleportation
  • Terrain Control is incompatible as there are too many overlapping features.
