Light Maps Lab

What's Happening

A light map is an additional texture layer that's used for displaying pre-rendered shadows. Objects without light maps (anything besides BSP geometry) use their vertices for determining lighting; with a light map, additional points (by default, one for every 16 world units) are used. This lab demonstrates the effects of changing the light map scale on faces in a WTStudio level; setting the light map scale to 0.5 uses lighting points spaced 8 world units apart, and setting it to 0.1 uses points spaced 1.6 world units apart. Try setting the light map scale to different values, and note how the shadows become crisper as the light map scale decreases.
