Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Trigger, teleportation and hidden object.

Hi
I try to create hiding objects like dirtpiles and also use teleportation to get my characters from one terrain to another.
I understood that I should use triggers, but I do not know how ...
In particular how to link them to an object.
Can someone help me?
