Modkit - Updated To Unity 2018
  • Updated modkit to use Unity 2018.2.8f1. You will need to download this version of Unity to use the latest modkit. For upgrading, I would strongly recommend starting a fresh project with the new modkit, and then copying over any scene or mesh data you want.
  • Portals can select different game mode based on player’s held item. (Place GrabbableItem with KeyId=Red in world and add GameModeTweak with RequiredKey=Red to GameModeContainer.) This replaces how buddy mode used to work.
  • Add named objects and NOT_PLAYER condition to ActivateTrigger
