Light sources do not seem to work correctly. Performed tests with completely indoor scenes that receive no lighting from HDRI or the “Sun.”
The problem is that after tuning off visibility or even deleting a light source, the scene continues to be lit. One potential fix is to move the whole model somewhere else, after which it once again becomes completely dark. Adding a light source once more causes the same problem.
