Mtl Render Stats

This page provides information about the Render Stats material in V-Ray for Blender.

Overview

The V-Ray Render Stats material can be used to specify additional render settings on a per-material basis. The same settings can be accessed through the Object Properties, but if this material is used, it overrides those from the object properties.

The same properties are also present in every shape of a Maya node. Those override both from this material and from the object properties.

Input Sockets

This section lists input sockets that are not found in the Properties tab but only as inputs for the node.

Base material – The input socket for the actual surface material.

Click CTRL + H to expand all the hidden input ports of V-Ray nodes. Not all V-Ray input ports are exposed, to save space, but if you need a specific port that is not visible, use this shortcut to show all of them.

Render Stats

Primary Visibility – When disabled, the object will not be visible. See the Primary Visibility example.

Visible In Reflections – When disabled, the object will appear perfectly transparent to reflection rays. See the Visible in Reflections/Refractions example.

Visible In Refractions – When disabled, the object will appear perfectly transparent to refraction rays. See the Visible in Reflections/Refractions example.

Casts Shadows – When disabled, the object will not be casting shadows. See the Cast Shadows example.

Receives Shadows – When disabled, the object will not receive shadows.

Visible To GI – When disabled, the object will be considered perfectly transparent to GI rays.

Example: Primary Visibility

This example shows the effect of the Primary Visibility parameter. The V-Ray Render Stats material is applied to the glass owl figurine.

When Primary Visibility is disabled, the glass owl figurine is not visible to the camera, but it is still visible in reflections and refractions and continues to cast shadows.

Example: Cast Shadows

This example shows the effect of the Cast Shadows parameter. The V-Ray Render Stats material is applied to the metallic owl figurine.

Example: Visible in Reflections/Refractions

This example shows the effect of the Visible In Reflections and Visible In Refractions parameters. The V-Ray Render Stats material is applied to the metallic owl figurine.

When Visible In Reflections is off, the metallic owl is transparent to reflection rays, and respectively when the Visible In Refraction is off, the metallic owl is transparent to refraction rays. When both options are off, the metallic owl is neither visible in the mirror plane nor in the glass owl figurine.
