We are going to experiment with some ways to amplify exterior lighting when it enters the interiors, so that exteriors and interiors would effectively use different light strengths. This should help in producing well-lit mixed exterior-interior scenes. Some potential approaches has been discussed in this thread: No collisions in VR - #3 by Michael_Campbell.
We’ll do some preliminary tests in October, and then we’ll have some estimate on when such a feature could be added.
