This page provides information on the Distributed Rendering (DR) tab in the V-Ray Renderer parameters.

Overview

Distributed rendering is a technique for distributing a single render job within a single frame across many computers in a network.

Parameters

 

 

 

Enabled – Enables additional parameters and settings needed to distribute the rendering across additional computers.

Default Port – Specifies the default port number at which the DR server operates. The default value is 20207.

Number of Hosts – Specifies the number of hosts to use for DR. This value controls the number of host input fields below.

Enabled – Enables or disables the specified host.

Host Address – Specifies a host IP address or network name

Use Default Port – When enabled, the Default Port number will be used.

Host Port – Specifies the port number for the host.

 

Step-by-Step DR Set Up

1. Set up the Render Servers. You can do that in two different ways:

  • Start the render servers.
  • Start the V-Ray Standalone and enter the vray -server command in the command prompt.

2. Set up the Render Client. In the Houdini interface, open the V-Ray Renderer properties and navigate to the DR tab. Add all the Render Hosts by inputting their IPs. You can include or exclude the servers in the list in the current rendering by toggling the Enabled option.

 

Notes

  • When you cancel a DR rendering, it might take some time for the render servers to finish working and they might not be immediately available for another render.

  • Servers can be added, removed, enabled, and disabled while running a CPU distributed render. For GPU rendering, DR settings can not be changed during the render. When using progressive rendering, nodes can only be added or enabled while rendering. While rendering, some of the options will be disabled. To make adjustments, stop the render first.
