World Creation GUI

Once you have clicked Single Player -> Create New World -> More World Options, then World Type a few times until you see World Type: OTG then Customize, you will be presented with this screen. This GUI allows you to assign OTG presets to the normal Minecraft dimensions (Overworld / Nether / End) or to add them as separate stand alone dimensions which can be accessed via a portal.
Clicking one of the normal Minecraft dimensions will allow you to choose from your list of installed presets which can be used for that world. Note that you do not need to use an OTG preset for these, you can also choose “Non-OTG” (which will present you with an option to choose a non-OTG world type) or “Vanilla” (which means OTG will not impact that dimension).

Clicking the Add button will allow you to add OTG presets as separate dimensions. Selecting an added dimension and clicking Remove will remove it. If you want to change the preset selection for an already added dimension, click Edit.

If you are a modpack developer and would like to assign some of these options as defaults without requiring user setup as above, please see the wiki section on modpack configuration.

I updated OTG and got an error!

When updating be sure to delete OTG-Core.jar from the 1.12.2 folder or it will not be updated.

Known issues (1.12.2):

Some problems with dimension management mods (RFTools) may occur, please report these on the OTG Discord or Github, thanks!

OTG does not support other mods’ biomes spawning in OTG overworlds/dimensions, however most modded resources and mobs etc do spawn in OTG biomes.
