You can set advanced lighting settings locally for specific objects using the Object Properties dialog box, as shown in Figure 28.5.
Figure 28.5: Use the Advanced Lighting panel in the Object Properties dialog box to disable advanced lighting.
At the top of the Advanced Lighting panel in the Object Properties dialog box is the number of selected objects and lights. This dialog box lets you specify whether this object should be excluded from the advanced lighting calculations. The properties can be set By Object or By Layer. If included, you can select whether the object casts shadows, whether it receives illumination, and how it handles Radiosity. The Number Regathering Rays Multiplier option sets the number of rays cast by the selected object. For large smooth surfaces, reducing artifacts by increasing this value can be helpful. The rest of the settings in this panel deal with Radiosity.
