Since it is difficult for a renderer to resolve interiors with little or no direct lighting, portal lights help direct the renderer's attention to the exterior source of light. 

To set up Portal Lights in Solaris requires the *portallight *LOP to be in the Solaris network before the domelight it will be attached to.

Once created, it can then be attached to the domelight:
