The new V-Ray Swarm is a web-based distributed rendering system. It’s a simple, yet powerful way to split your rendering across multiple computers.


Each machine participating in the render job requires a V-Ray 3.0 Render Node license. This includes the workstation initiating the rendering process.




UI Path: ||V-Ray Asset Editor|| > Settings > Swarm rollout





Enabled – Turns Swarm, V-Ray's web-based distributed rendering system, on or off.

Goal Slider – Sets the desired percentage of utilization of available resources. Computers added or removed to V-Ray Swarm will be taken into account automatically.

V-Ray Swarm ( ) – Opens up the V-Ray Swarm web interface of the current Master Node machine. Alternatively, it can be accessed by typing in the IP address of the current Master Node machine on the default port 24267. This allows you to see the swarm render node machines available for rendering jobs in your network. You can see which of the render node machines are connecting to the particular machine that is casting out the render to the Swarm by the IP address next to its status. This interface allows you also to configure the render node machines, tag them, or monitor their resource utilization while rendering.




Tags allow you to tag this node with a descriptor that defines something about the machine, which we can later use to selectively control from inside of Rhino.

For example, tags can denote if this machine is one of a few that have a powerful GPU, or if a machine is not a workstation and a node on a render farm.

For information on how to use Tags, see the Swarm Configuration page.



Once the render process is initiated, machines marked with the selected tags will load the scene and assist with the rendering. This is noted in both the Progress Log and the Current Usage bar located in the Swarm settings section.

All scene assets need to be transferred from the local machine to each render node machine before they can begin working on the job. If a render node machine's V-Ray version differs from that of the local host machine, V-Ray Swarm will upload the needed builds automatically and will ensure that all the render nodes will use the same V-Ray build.





The blue marker displays what part of all available machines are rendering the job, and the red marker shows the machines currently occupied with another job. More detailed information on the Current usage bar is displayed upon mouse-over. 

The Goal slider beneath the bar can be adjusted dynamically to add or remove assigned machines during the rendering process. 


Network Discovery

The Network Discovery settings control how a Master Node is selected. The Master Node is the machine which can communicate with the greatest number of render node machines. By default, V-Ray Swarm's Network Discovery is set to use auto-discovery.



If the Auto-Discovery option is turned off, the custom configuration of the manually set Master Node becomes available. This option is suitable if there is more than one subnet in the LAN, or if you want to dedicate one or more machines to be Master Nodes. You may choose three machines as Primary and Alternate Master nodes. Alternatively, the Network Discovery settings can be adjusted through the V-Ray Swarm web interface.


For information on Network Discovery, see the Swarm Configuration page.


Cap CPU Utilization


When enabled V-Ray will exclude your machine from rendering; however, Swarm will continue to use a small percentage of the local machine's resources to communicate with the render node machines.
