im trying to do some lighting for the first time and im not really happy with the results. theres a lot of spots that are really dark although theres a light source or window closely nearby. some large brushes also receive a lot of weird looking shadows. ive set light_environment brightness up to 4000 and Ambient up to 3000 which hasnt helped that much. id like the map to be rather bright, is there another way instead of cluttering everything up with lamps?
