[MDL ED] Custom door - sounds not working as they should

[The chaser]

Haven't you tried copy-pasting the main settings from the original doors? It's just easier.

The door sounds go in the joint. This joint controlls the body, which controlls the mesh. Just go to View<Outline and assign the parent and the child (the joint parent is the small and non-gravitatorial body which you set in the invisible part of the door (the hinges) and the child of the joint is the body which contains the door's mesh.

Just some tips. Try deleting the entity and making another one with these settings, just in case.
