The Rays panel allows you control for all of the controls related to ray tracing and indirect illumination. Many of these settings can be overridden on a per ensemble basis.

General Attributes
Max Specular Depth - Limits the number of specular bounces (reflections and refractions) for
rays trace from the associated primitive. To resolve the interaction
between per-primitive values, we pass the current max down the ray tree
and apply MIN(ray.depthMax, primitive.depthMax + ray.depth). You can
use this attribute to limit the number of reflection and refraction bounces
and thereby tune your rendering speed. A value of 1 or 2 is a reasonable
default unless you need multi-bounce effects.
This value acts as the scene default and you can override this
value on a per-primitive basis via the Slim Ensemble. Sample Motion - Controls whether motion blurred objects appear in ray traced results. If your reflective object is moving or deforming you should disable this parameter to avoid self-intersection artifacts. If your mirror isn't moving, set this to 1 to see the reflected objects properly blurred. |
