Mirror Material

Mirror

Mirror is used for planar surfaces that produce secondary source reflections. It should be used sparingly, as it may cause the light source calculation blow up if it is applied to many small surfaces. This material is only supported for flat surfaces, such as polygons and rings.

Color:
The color values will modify the reflectance.

[0.0 0.0 0.0]

black (full absorption)

[1.0 1.0 1.0]

white (no absorption)

Values lower than [0.01 0.01 0.01] or higher than [0.9 0.9 0.9] are rare.

Viewed Material:
This option allows to assign another material to the mirror for when it is viewed directly. You can chose from all material definitions known to the current project. There are two special "materials":

-- visible mirror --

This means that the surfaces will just behave as a true mirror in all situations, whether in the reflectance calculation or when viewed directly.

-- invisible mirror --

The mirror will disappear when viewed directly. This is only apropriate if the surface hides other, more detailed geometry with the same overall reflectance
