One of the innovations implemented in new Maya 2008 is the portal light. The portallight is used in interior lighting, is a shader that connects to a area light for channeling rays of the phisical sun + sky that are lost in our interior scene to go to better illuminate areas not exposed to direct sunlight or skylight. Use the mia_portal_light shader to create a portal light to reduce final gather rays and rendering times.

 

 

 

This new feature Portal light is great for interior renders!
