Objects Not Receiving Shadows

Upgraded a project to 5.4.0b11 (to work with the Rift). After rebaking (which seems be be requisite when moving to a new version of Unity), object that were receiving realtime shadows in Unity 5.3 are suddenly not. Nothing was changed in the scene between the two versions, but where there were Realtime cast shadows - now there are none.

Any leads I should start chasing down?

Do you have mixed or realtime lights? Please post a screenshot of the settings in the lighting window.

The light on it is currently set to Mixed. However, I’ve tried putting a Realtime only light on it, and (After Baking) the door simply will not receive shadows.

Here are the screenshots of the light settings and the results (and the door’s settings if that makes a difference):
