| - | ===== Radiosity Area Light Sources ===== | + | One of the key questions that mappers frequently raise is how to define and place light sources. |
| + | While placing light sources is generally easy, this section explains the types of available lighting techniques in Ca3DE and the options to create light sources for each. | ||
| - | Nearly every texture in ''Games/DeathMatch/Textures'' that looks like a light source, is a light source. | + | The Ca3D-Engine implements two different types of lighting techniques: |
| - | That is, such textures are defined to actually emit light. | + | * Radiosity lighting and |
| - | Thus, there is hardly ever a need to use "Isotropic Point Light" entities at all. | + | * dynamic lighting. |
| - | Please have a look into the ''CaLight.cfg'' file for a list of textures that emit light, | + | |
| - | but for future compatibility you should not make changes in this file (except for your own new textures). | + | |
| - | + | The two lighting techniques are quite distinct from each other, and each comes with a set of feature of its own. | |
| - | + | ||
| - | ===== Sky Light ===== | + | |
| - | + | ||
| - | You can add sky domes to your world by applying the "sky" texture to the "ceiling" surfaces. | + | |
| - | You also have to set the sky name, sunlight direction, and sunlight irradiance (intensity and color) in the **Map properties** dialog. | + | |
| - | The table below lists a few examples in order to give you a rough idea about what to enter. | + | |
| - | (Don't worry if you have initially forgotten to enter these settings in the **Map properties** dialog. | + | |
| - | The CaLight tool that you will use later gives you a second chance to override them (see section [[Mapping::Compiling#CaLight]]).) | + | |
