The Optimizations rollout provides additional controls for Advanced Ray-traced Shadow and Area Shadow generation.

Interface

Transparent Shadows group

On

When checked, transparent surfaces will cast a colored shadow. Otherwise, all shadows are black.

NoteShadows will generate faster with this value turned off.

A stained glass appears solid with the transparency optimization turned off.

Antialiasing Threshold

The maximum color difference allowed between transparent object samples before antialiasing is triggered. Increasing the value of this color will make the shadow less sensitive to aliasing artifacts and improve speed, decreasing the value will increase the sensitivity, improving quality.

Antialias Suppression group

Supersampled Material

When on, only pass 1 is used during 2-pass antialiasing when shading a supersampled material.

NoteWhen off, rendering time can increase without resulting in a better image.
Reflect/Refract

When on only pass 1 is used during 2-pass antialiasing when shading reflections or refractions.

NoteWhen off, rendering time can increase without resulting in a better image.

Coplanar Face Culling group

Skip Coplanar Faces

Prevents adjacent faces from shadowing each other. This is of particular concern at the terminator on curved surfaces such as spheres.

Threshold

The angle between adjacent faces.

Range = 0.0 (perpendicular) to 1.0 (parallel).
