In the exploration area there is a particular generic base that looks like some turned the lights all the up to Sun bright (the one with star chart walls).
In this area I've noticed that any dialogue screens and my officer portraits all appear dark, like they are standing in the shade (probably to make sure they don't get sunburnt!).
Notice how shaded the officer portraits look. It is the same when a dialogue window pops up.
In fact anything targetted (any creature) appears the same shaded way in their portrait window.
I have turned off bloom (I generally don't like bloom effect), mainly because it becomes painful in this generic base.
Yeah, all the character models in the U screen also get this "shadow" look.
I think all character models showing in the interface should be shown in the same "light" regardless of the environmental lighting.
