Find this section in some selected objects’ Attribute Editor, from the Attribute Spread Sheet (Windows > General Editors > Attribute Spread Sheet) or the Rendering Flags window (Windows > Rendering Editors > Rendering Flags).
The Render Stats section appears in the Attribute Editor when applicable to the selected object. These options lets you turn on or off various rendering options for selected objects.
Determines whether the surface casts shadows. To make shadows render faster, turn off Casts Shadows for surfaces that do not need to cast shadows.
Enable Casts Shadows if you want the object's shadow (cast onto other objects) to render. Disable if you do not want the object's shadow cast onto other objects to be rendered.
Turns on the shadow-catching ability of the surface.
Enable this option per object, so that the object renders transparent and shows directly through to the background environment; for example, an image plane. For use with Viewport 2.0. Shadowing (Receive Shadows) is supported with this feature.
Artifacts may appear on objects with the Hold-Out option enabled if these objects also have shadows enabled.
In a scene where Screen-space Ambient Occlusion and Multisampling Anti-aliasing are used, objects with the Hold-Out option enabled may block image planes. To work around this issue, disable Screen-space Ambient Occlusion and Multisampling Anti-aliasing.
Turns on motion blur for the surface. You must also turn on Motion Blur in the Render Settings window.
When on, the surface is included in software renders.
A surface’s shadow renders, however, if its Primary Visibility is off and Cast Shadows is on. This also applies to reflections and refractions.
If this is on, each vertex uses its own normal vector - meaning smoother transition between two faces. If this is off, one normal vector is used for a face; 3 vertices in a triangle uses a same normal vector, resulting flat looking shading.
When on, the surface reflects in reflective surfaces.
When on, the surface refracts in transparent surfaces.
Determines if the surface is double-sided. If single-sided, you can decrease memory use and use the Opposite option.
Opposite flips the surface normals. Double-Sided must be off to set Opposite.
When on, the surface overrides the geometry anti-aliasing settings.
Select one of the following options:
The default. It takes 32 visibility samples.
Takes 96 visibility samples.
Takes 288 visibility samples.
Takes 512 visibility samples.
Takes 800 visibility samples. Level 5 gives the best edge anti aliasing quality, but it is also the most expensive (in both memory and speed).
When on, the surface overrides the global shading sample settings in the Render Settings window.
Sets the minimum number of times Maya samples each pixel. For example, if set to 1, Maya samples each pixel once; if set to 8, Maya samples each pixel 8 times. The number of shading samples taken per pixel is limited by the number of visibility samples performed by the Edge Anti-Aliasing computation. So, if you use Medium Quality (which performs 8 visibility samples per pixel), you cannot get more than 8 shading samples regardless of the Shading Samples attribute setting.
Since Shading Samples computation is very expensive, you should try adjusting the Max Shading Samples (below) first.
Sets the maximum number of times a pixel is sampled during the second pass of a Highest Quality render (adaptive shading pass). The higher the number, the longer the rendering takes, but the more accurate the resulting image is.
Max Shading Samples has an effect only when used in conjunction with Highest Quality edge anti-aliasing. Also, depending on the requirements to compute an accurate solution, the number of Shading Samples taken can be less than the number of Max Shading Samples.
Select this option to indicate that the image plane already has a pre-multiplied alpha channel; that is, the RGB values have been multiplied by the alpha channel.
The following attributes are only applicable to volume primitives and fluid shapes. They only appear in the Attribute Editor of the shape node of a volume primitive or fluid shape.
When on, the object overrides the global volume shading settings and you can turn on the Depth Jitter option in Render Settings window.
Adjusts the number of samples placed inside the fog volume.
If you set Volume Sample Override on, you can turn on Depth Jitter option. Randomizes the samples of the volume with depth which replaces banding artifacts in volume renders with noise. The noise can be dramatically reduced by increasing the volume samples and anti-aliasing levels.
