3. I'll list the most important properies here. Be sure to try each one on your own.
Brightness : Prety obvious, it's how bright the light appears.
FalloffExponent: : How sharp or soft the light's fall off appears within its radius.
Move your light close to a wall and adjust this value, and you'll see how it works.
LightColor : The color of the light muliplies against the brightness seing. So if
you pick a bright color but a low brightness, it'll look dark in the scene.
Radius : The area of the level that is affected by the light. A wireframe sphere is
drawn around the light in the level to help you visualize. You can also adjust this
by using the scale tool on the light in the scene.
Other properies are generally best let at their default values, though we'll discuss
some of them later.
4. For now, make your light a rich orange color with a fairly high brightness and a
radius large enough to fill your room.
Placing a spotlight is a litle harder than placing a point light—they can be found under the
Actor Classes browser.
So open your generic browser and go to the Actor Classes tab. Open up the Light
category and select Spot Light . You'll noice two subcategories, SpotLightMovable
and SpotLightToggleable . These are mainly used in animaion sequences or hooked
up to gameplay, so ignore them for now.
Right-click in your scene and select Add SpotLightHere . A white spotlight appears,
poining down. Move it so that it's casing a circle of light on the ground.
