	Deciding on the best level of [[Ambient Light]] can be tricky. If you make it too bright, the mission can take on a flat, washed-out feel and useful shadows can be difficult to distinguish from their surroundings. Too dark, and it is often hard to see your immediate vicinity. The '''dark vision''' technique allows you to light up nearby objects while leaving distant areas ~~dark~~.

If you make it too bright, the mission can take on a flat, washed-out feel and useful shadows can be difficult to distinguish from their surroundings. Too dark, and it is often hard to see your immediate vicinity. The '''dark vision''' technique gives you the best of both worlds: it allows you to light up nearby objects so you can see them while leaving distant areas nicely unlit.
