Placing lights
You can place lights wherever you want and however you want. To add more lights, just duplicate the existing ones. Remember to add each light to a numbered group, so they look pretty with cues. You can have as many numbered groups as you want. For example, you might have lights named Fix1, Fix2, Fix3, ..., Fix20.
Follow spotlights currently work correctly only when they're placed on the floor or ceiling. They'll not work correctly when the model itself is tilted.
Light sources in LEDs
LEDs do not come with a light source by default. They'll instead use a light source (PointLight, SpotLight or SurfaceLight) named Light that you insert into it. It's optional. The brightness of the light in the properties decides how bright it'll be in game. You can disable the light in Studio for convenience, it'll enable itself when needed in-game.
