Quality Properties

The Quality object properties

Shading Rate Multiplier

Controls the shading rate on a per-object basis. The specified value multiplies the global shading rate set in Quality.

Global Illumination Shading Rate Multiplier

This controls the shading rate during the "bake" phase of the point-based global illumination algorithm.

Smooth Subdivision Threshold

When applied to a polygon mesh primitive, specifies the level of geometric approximation from which the object will be rendered as a subdivision surface instead of a plain polygon mesh. For example, if the Render Level subdivision property (in Geometric Approximation) is set to 1 and this property is set to 2, then 3Delight for Softimage will simply render a polygonal mesh that has been subdivided once. But if you set this property to 1, then 3Delight for Softimage won't subdivide the mesh and will render it as a perfectly smooth subdivision surface. It is better to render subdivision surfaces instead of subdividing polygonal meshes too much. The default value is 1 (3Delight for Softimage will render mesh as smooth subdivision surfaces as soon as geometric approximation Render Level property is bigger than 0).

High Quality UV Interpolation (FaceVertex)

When applied to a polygon mesh primitive rendered as a subdivision surface, enables a method of interpolation for surface attributes that follows the subdivision rules more closely, eliminating many visual artifacts due to bilinear interpolation.

Displace Vertices Only

Enable the vertex level displacement. Geometry is pre-tessellated to a given amount of subdivision prior to running the displacement shader.

Subdivision Steps

Amount of pre-tessellation subdivision steps for the vertex level displacement.
