Do me a favor, and change the material of ELEMENT 3 of the door. (Around the 0:30 mark).
Choose any other material you’d like.
If the door does not glow, then it is DEFINITELY the material.
The fact that it is that bright WITHOUT light makes me think that there’s an emissive quality in the material instance… (I doubt the parent material, because EVERYTHING would look bright… assuming that the parent material is used for many/all of the other meshes/assets).
(PS: I’m ignoring what you said about the box, for now. I want to rule out the material first.)
