This page provides information about the Object Select render element in V-Ray for Cinema 4D.
Overview
The Object Select Render Element stores only the object(s) called out with a specific Object or Material ID.
This effect is reversible to create a render element that excludes a particular object or objects according to Object or Material ID.
When rendering this element out, it will also include a filter and alpha pass separately to help make it easier to use when compositing.

How to add a render element to a scene
Properties
Enable Deep Output – Specifies whether to include this render element in deep images.
Use Multimatte ID – When enabled, the pass considers the Material ID and renders accordingly. When disabled, these values are considered to be the Object ID.
Affect Matte Objects – Determines whether to include matte objects when generating the render element.
Consider for Anti-Aliasing – When enabled, anti-aliasing is used where possible.
Invert Selection – Uses the opposite of the selected objects in the render pass.
Denoise – Enables the render element's denoising, provided the Denoiser option is enabled.
Color Mapping – Applies the color mapping options specified in the Color Mapping rollout of the V-Ray tab in the Render Settings window to this render element.
IDs Selection Mode – Specifies the selection mode:
Single ID – Allows you to select only one ID to be included in the render pass.
Range IDs – Allows you to specify a range of IDs to be included in the render pass.
Custom IDs – Specifies a list of IDs included in this render pass.
ID – When the IDs Selection Mode is set to Single ID, you can specify that ID in this field.
Range Start ID/Range End ID – When the IDs Selection Mode is set to Range IDs, you can specify a start and end value of the IDs.
Custom ID – When the IDs Selection Mode is set to Custom IDs, use this field to enter the IDs.
Example Use Case
The background is isolated using the Object Select RE. The selection is then edited in a post-production software (Photoshop, Gimp, etc.) to change its color. The edited background is then added back into the render. See the render before and after.
