Two questions 1) What do you recommend as far as baking in lighting? It would seem that if you have a scene where day changes into night, baked lighting would be a issue. 2) How do you handle a dark room/cave in a open world scene with enviro? Normally, you adjust the ambient lighting in the scene so that a room or cave in an open world setting would be dark when you go inside. However, enviro overrides any ambient light settings for the scene.
