How do you create an entity that collides?

[Mackiiboy]

I'm almost done with my custom story and I'm creating a hidden "easter egg"-part in my story that leads to the world of "Legends of Zelda". Therefore, I've collected some Zelda models from Ocarina of Time and edited them in Maya, exported them as a .dae file and imported them to Amnesia with the ModelEditor.



The problem is that the entities do not collide, you can walk right trough them. I've tried with settings > User defined variables in ModelEditor to find some settings for this, but that does not seem to work for me.
I've compared with other entities in the ModelEditor and concluded that the other entities have a body, maybe that's the problem?

If ya know what to do, please comment
