The objects are considered to be part of a "prelit" sub-scene, where direct and indirect lighting is baked into the shading. They will reflect light from and towards regular objects in the scene but, just as matte objects, they will appear as transparent black pixels in the primary output variable. This is used to implement Prelit Materials as described in Prelit materials: light transport for live-action elements in production rendering.
