The character texture detail slider is doing odd things at the lower end which it isn't doing on live or redshirt.
If it's lowered to 63 or 50% (the bottom two "notches"), all characters get a dark shadow above their right eye, sometimes extending to the cheek or neck. At 75% the effect usually disappears from NPCs, but sometimes persists in the contact window as high as 100%. Some NPCs (Captain Brott) don't seem to shed theirs shadows until even higher than that.
edit: Some NPCs also have extremely bright lights shining on their right legs.
