Portal Material


The PortalA technique that assists the render kernel with exterior light sources that illuminate interiors. In interior renderings with windows, it is difficult for the path tracer to find light from the outside environment and optimally render the scene. Portals are planes that are added to the scene with the Portal material applied to them. MaterialThe representation of the surface or volume properties of an object. optimizes rendering by helping the render kernel find important light sources in the scene. See Portals for details on how to set them up. Geometry that has a Portal Material applied to it becomes invisible to the render.
