scene load

Hi. Does anyone know if there's a way to have passthrough on while loading a scene? If not, it would be great to be able to change the default black background color to enable that. It's lonely in the dark :)

So a couple of days ago I threw together a scene that had quite a bit of timeline animations, effects, etc. Now all of a sudden I can't load this specific scene. I get this error code: !> Exception during load System.OutOfMemoryException: Out of memory at (wrapper managed-to-native)...
