Calculate Lights

To calculate scene lights and shadows, select the Tools>Calculate Lights menu.  The Light Settings dialog will allow you to adjust various parameters before performing the operation. 

 

 

 

Press the OK button to perform the operation.  If no scene lights are present, the entire scene will be colored the ambient lighting color.  Caution should be taken when using a smaller lightmap size.  If a surface in the scene is larger than the lightmap area, the surface may only be  partially lit.
