Great, but what does all this mean to me?

Texture Lights are what make your level look dark or light or both. I usually wait until my level's complete to add lights, but you certainly don't have to. Don't expect to get it right the first time either. You'll learn how to space them, adjust them etc... Cube Light brightness affects OBJECT brightness; robots, ships, etc... To learn about Blinking Lights, see the Textures section of this guide.

• Open the Texture Edit Box .
  
  
• Select the cube's side on which you want the light affixed.
