====== Trigger Points ======
TriggerPoints are 3D positions in your 3D world space. Those can be static or dynamic (moving). For example you have another character you want to talk to. You can set up a dynamic trigger point for the model and the system will automatically check when it's getting close enough.
In a triggerpoint specific event you can react on that feedback and start the conversation ([[Dialogues|Dialogues]]).
