I should reiterate, the interiors are VERY work in progress. The only thing final about them is their layout; custom entities are being made, and barely any decals have been slapped down. Thus, comments like "the room needs details" are redundant and already on my list.
however, the comment on the volume was helpful, since it was the purpose of this video to focus on the flares. I am trying to make a particle system work with them too, and all this video is is a test of how they will be working in-game. They'll likely be prettier in the final.
