Use this node to set your options for your render pass.
Render Pass Options
Use this attribute to sort your render passes into logical file groups. The pass group name that you enter in this field is appended to the image file name when you include the <RenderPassFileGroup> render token in your File name prefix attribute in the File Output section in the Render Settings: Common tab.
For example, group your diffuse, specular and shadow passes into a pass group called Illumination. When rendering with openEXR, add the <RenderPassFileGroup> render token to your File name prefix attribute. All passes with Pass Group Name set to Illumination are concatenated under the Illumination exr file.
A render pass node may also have several of the following attributes, depending on the pass type:
Framebuffer values are modulated by material transparency. Only available for render pass types where it is pertinent. For example, if you render a 50% transparent surface and the object behind it is opaque, the diffuse for the opaque object is dimmed by 50% and written as is, since the object is being seen through a transparent surface.
Normalized 2D Motion Vector render pass attributes
The Normalized 2D Motion Vector pass node also includes these attributes:
If the Automatic Max Pixel Disp. option is selected, Maya calculates the maximum image resolution. For example, if the image resolution is 640x480, the biggest axis of the image, 640, is used.
Otherwise, if the Automatic Max Pixel Disp. option is disabled, Maya uses the value specified in Max Pixel Disp.
Camera Depth render pass attributes
The Camera Depth pass node also includes these attributes: Near clipping plane / Far clipping plane, and Minimum buffer value and Maximum buffer value.
Use the attributes to normalize the camera depth value. For example, using the default values, any value less than 0 is normalized to 0 and any value greater than 1000 is normalized to 1. Alternatively, you can also use these attributes to clip objects out of the scene. You must enable the Remap Depth Values option in order for the near and far clipping planes and minimum and maximum buffer values to take effect.
