Cheaper Price in DESCRIPTION Mythic-Interiors
This is the basic frameworking for the spawnable interiors. Call any of the functions passing a spawn point and it will spawn objects there and then teleport the player.
You do need the custom objects in the stream folder along with the YTYP files defined in the resource manifest.
