Output Pass

Several types of output passes are supported, the default pass is Beauty which renders all the effects and features enabled. This attribute is very useful for tuning some final render properties and for multi-pass output. See Output Settings Node for more details on multi-pass rendering and output. These render passes are available:

• BEAUTY - Compilation of other passes, this is what the final result will look like.
• DEPTH - Screen space depth values mapped to grey scale.
• SURFACE COLOR - Color of all surfaces (ie. just color attribute in material properties).
• AMBIENT - Ambient color of all surfaces.
• INCANDESCENCE - Incandescence color of all surfaces.
• DIFFUSE - Diffuse intensity (grey scale) of all diffuse lights applied on surfaces.
• SPECULAR - Specular color of all specular lights applied on surfaces.
• AMBIENT OCCLUSION - Intensity of ambient occlusion in scene.
• COLOR BLEEDING - Indirect illumination from color bleeding pass only.
• SHADOWS - Only shadows are rendered. Result should be multiplied with the original layer to add shadows.
• SHADOW REGIONS - Display shadow regions for Cascaded shadow maps only (see Light Node).
• REFLECTIONS - Only reflections are rendered. Result should be added to the original layer to add reflections.
• AMBIENT LIGHT - Contribution of all ambient lights in scene.
• NORMALS - Normals of all objects (world-space)
• TEXTURES SIZES - Show textures sizes related to screen resolution (see Textures Sizes Settings below).
• FLUIDS, PARTICLES - Only fluids and particles are rendered.
• MOTION VECTORS - Renders screen-space motion vectors in RG channels. Value (0.5, 0.5) means no motion.
• STEREO DISPARITY (experimental) - Display stereo disparity information. Useful for tweaking stereo cameras.
• ALPHA - Display only alpha channel from rendered frame.
• UVs - Display UV coordinates of all objects.
• Indirect lighting - Display only indirect lighting in scene.
• Wireframe - Display all objects as wireframe. Color can be changed by Wireframe Color attribute.
• Primary lighting - Display only primary lighting in scene.
• Transparency - Display only all transparent objects.
• SSS - Display only all sub-surface scattering objects.

NOTE: All output passes follow the same rules and use other render settings in the same way. It means it is possible to add blur or glow for example to any of the passes (which is not a good idea if the passes are to be combined in post processing) or if ambient occlusion pass is selected for example but global AO feature is disabled, nothing but white color will be output.

Output Bit Depth

Number of bits per channel for internal and output render buffers. Note that not all output file formats are able to handle all depths.

Render To Viewport

Enable or disable rendering to viewport.

Render Selection Set

Choose one from Maya sets to be connected with this render settings. If is selected 'no selection', then will be rendered all objects visible in scene, otherwise will be rendered only visible objects in selected set. Note that this attribute is used also for Isolate selected option.

Other Matte

If selected, objects other than those specified by the set set in Render Selection Set attribute, will be rendered as matte objects.

Alpha Objects Order

Semi transparent objects will be rendered in selected order.

Gamma & Light Correction

Options for gamma correction, useful for liner workflow.

Viewport Gamma Correction

Gamma correction for render to viewport. For gamma correction for output render see Output Settings Node. The gamma from Render Settings and the gamma from Output Settings will both be used in the output file image!

Material Gamma Correction

Inverse gamma correction for materials. Used to balance Viewport Gamma Correction.

Lights Gamma Correction

Inverse gamma correction for lights. Used to balance Viewport Gamma Correction.

Physically Correct

When enabled,  primary light is reduced by amount of bounced light. That prevets unreal accumulating and multipling of light rays.

Raytracing

Ray Bias

Bias for raytracing. Can help remove artefacts in scenes of large or small scale.

Max Ray Length

Maximum distance that any ray can achieve. For example: two objects can not reflect or illuminate each other, if distance between them is bigger then radius attribute.

Max Ray Intensity

Maximal intensity value for each secondary rays in global illumination. It can be helpful if it in scene objects with large intensity. This intensity is distributed in scene and can cause very noisy results, which is very badly reduced by adding rays count. White dots problem

Intensity Multiplier

Intensity multipiler for raytracing, should stay on 1 for realistic results

Noise Seed

Seed value of noise pattern used for raytracing.

Light Threshold for Shadow Rays

Light threshold can be used for some speedup while tracing shadows rays in indirect lighting. Shadow rays will not be traced if light intensity is smaller than specified threshold (default is 0). You can also specify shadow intensity in this case.

Threshold

Light intensity threshold value. If light intensity is smaller than this value, shadow rays will not be traced.

Shadow Intensity

If shadow rays will not be traced, then use this intensity of shadow (0 means that light is not shadowed, otherwise 1 means that light is shadowed)-
