Lighting your level is mainly about making sure the level is appropriately lit so that the player can navigate correctly through your level. It also means ensuring you have placed the correct type of light sources i.e. directional, point, spot or sunlight within the level so that it adds to the atmosphere created in your environment and if necessary supports any mechanics used in the level.
In this post I will briefly describe how lighting can be used within level design. The brightness and colours of lights used to light your level will all depend on the type of atmosphere you want to create. Any colours used below are examples and by no means a strict rule of how to light your level.
