Features

 Motion Blur

Motion Blur

RenderMan® renderer motion blur is true 3D motion blur and usually does not increase memory usage (at least for PRMan and 3Delight). In some instances, large amounts of motion blur can even decrease render times!

The Motion Blur setting enables rendering of motion blur. Two types of motion blur are available:

Motion Blur Length [0..1]

Use this setting to define to what degree objects should be blurred. A value of 1 will cause the blur to occur from one frame to the next; a value of 0.5 will reduce the length of the blur by half; a value of 0 will result in no blur taking place. Values greater than 1 are not recommended.

Motion Factor [0..10]
Motion Factor [0..10]
Motion Factor [0..10]

Use this setting to define if and how the number of shading samples should be adjusted in blurred regions. In areas affected by motion blur you can usually get away with using less shading detail. The Motion Factor setting reduces the shading rate based on the strength of the blur. A value of 0 will not reduce shading samples in blurred areas. The default value will reduce the shading in proportion to the blurriness. Higher values will reduce shading detail even further, which is what can ultimately lead to blurred areas rendering faster.

 Depth of Field

Depth Of Field

The Depth of Field effect is similar to motion blur. It is a true 3D effect and not as computationally intensive as motion blur.

Use Camera Setting
Focal Distance [-∞..+∞m]

When enabled, the camera’s Focal Distance setting will be applied (the focal distance is the distance at which objects will appear in focus).

Focal Length [-∞..+∞]
F-Stop [-∞..+∞]

These settings behave similarly to the same settings of a real world camera but are not based on a physical camera model.

Focus Factor [0..32]
Focus Factor [0..32]

This is an additional parameter for 3Delight/PRMan. It is the equivalant to the Motion Factor parameter. PRMan and AIR also use Motion Factor for depth of field.

 Ray Tracing

Trace Max. Depth [1..64]

This setting reflects the maximum recursion depth to which rays will be traced and is similar to Cinema 4D’s default Ray Depth value.

PRMan contains two additional settings:

Max. Diffuse Depth [1..64]
Max. Specular Depth [1..64]

Maximum Diffuse Depth, separated into diffuse and reflective samples.

Trace Bias [0..10000m]
Trace Bias [0..10000m]
Trace Bias [0..10000m]

Use this setting to correct any artefacting that may occur when, due to imprecise numerical calculations, traced rays meet the same surface from which they are traced. The Trace Bias value may have to be increased when working with larger scenes where artefacting occurs. Smaller scenes may require lower values to ensure reflections and rays are calculated correctly. In general, the default value can be used.

Sample Motion
Sample Motion

Here you can select whether or not motion blur should be accounted for when applying ray traced effects. When enabled, motion blurred objects will be rendered as blurred in reflections and other raytraced effects.

AIR has a similar setting called Trace Motion Blur.

Trace Displacements
Trace Displacements

When enabled, geometry will also be rendered as displaced in reflections. If disabled, displacements will be rendered as bump maps in reflections and other raytraced effects. Disabling this setting can save a lot of render time for certain scenes.

Specular Threshold [0..180°]

This threshold value defines the point at which a ray is counted as a diffuser or reflective ray (see also "Max. Diffuse Depth" and "Max. Specular Depth").

Trace Max. Depth [1..64]
Trace Max. Depth [1..64]

This setting reflects the maximum recursion depth to which rays will be traced and is similar to Cinema 4D’s default Ray Depth value.
