Enables motion blur for the entire scene. 3Delight will produce a 2-step linear motion blur unless an object or transform overrides this default to something elsefor additional steps. Refer to The Object Attributes.
Max Diffuse Depth
Sets the maximum bounce depth a diffuse ray can have. Diffuse depth count is incremented bounces are counted each time a ray hits a diffuse surface.
...
Sets the maximum bounces a reflected ray can reach. Reflection occurs when a ray bounces in the same hemisphere as the surface normal. Reflection rays include both mirror reflection and soft reflections due to rough surfaces. Setting this value to 0 will diable reflection bouncesdisable reflections.
Max Refraction Depth
Sets the maximum bounces a refracted ray can reach. Refraction occurs when a ray bounces in the opposite hemisphere of the surface normal. Refraction rays include " hard " refraction and soft refracton due to rough surfaces.
Max Hair Depth
Sets the maximum bounce depth a hair ray ray can have. Hair depth count is incremented bounces are counted each time a ray hits another hair (that is a surface with a Hair and Fur material applied).
Max Distance
This sets the maximum distance a ray can travel in the scene. If no objects are hit before within that distance the ray will only return illumination from light sources (including environment).
