Use Render Elements – A toggle for quick enabling and disabling of the render elements.
Templates – Specifies the render channel template from Back to Beauty, Back to Beauty Adv, and All Elements.
Generate – Generates render channels from a template.
Network – Specifies the V-Ray Render Elements ROP to use with the current Renderer. Multiple V-Ray Renderer nodes can link to the same Render Elements node.
Store All Render Elements Under Separate Folders – When enabled, it stores all render elements in separate folders. Works only if the file path does not contain ${AOV}.
Store Beauty Pass Under a Separate Folder – When enabled, it stores the Beauty pass in a separate RGBA folder.

${AOV} or only $AOV can be used to mark where RE.name will be placed in the filename. It can be used as a folder name too. The ${AOV} / $AOV tag is added to the File Path field.
If a ${AOV} / $AOV tag is present, V-Ray automatically exports individual files for each render element.
If there is no ${AOV}/$AOV tag specified and the render element supports any multichannel format, it is written in a multichannel format (.exr for example).
Starting with V-Ray 6 for Houdini as well as in the latest V-Ray 5 stable nightly builds, the Back to Beauty Adv preset includes all the needed Render channels - the DirectLight, GI, Reflection, and Refraction channels have been added recently too. Find more information about the channels included in the Back to Beauty Adv preset here: List of Supported Render Elements.
In order to render a correct Raw render pass, you need to also render the corresponding main element and filter. For example, Raw Reflection requires you to render Reflection and Reflection Filter. For Raw GI, you need GI and Diffuse, etc.

Memory Frame Buffer – Tells V-Ray how to utilize the VFB when rendering to .vrimg or .exr.
None – Doesn't display the image to minimize memory usage. Full – No memory optimization. Preview – Displays a lower resolution of the image to minimize memory usage.
Write Deep Data – When enabled, writes deep output into the rendered image.

Deep multipart EXR files are not supported.
Save Color Corrections to Raw Files – When enabled, the Color Corrections are saved into raw files. This options is available only for .exr and .vrimg files.
Save Cryptomatte Separately – Saves the Cryptomatte channels as a separate EXR file in the same location where the Beauty output is. The option is available for both V-Ray CPU and V-Ray GPU rendering.
Save Deep Data to Separate Files – When enabled, deep data is saved to separate files.
File – Deep render file path. A file without one of these extensions is given .exr extension by default. Compression – Compression type for the .exr files. Bits per channel – Stores 32 bit (single precision) color channels in the shade map. When disabled, 16 bit (half precision) values are stored.
Don't Save RGB Channel – When enabled, the RGB channels is not saved (ignored with multichannel exr and vrimg).
Don't Write Alpha Channel – When enabled, the Alpha channels are not saved (ignored with multichannel exr and vrimg).
Separate Alpha Channel File – When enabled, the alpha channel of the rendered image is saved to a separate file.
Save Velocity 0-Base – When enabled, it saves the velocity channel with zero base instead of the default 0.5 based.
Frame Stamp – Turns the frame stamp on and off.
