This page provides information on how to use the V-Ray Swarm distributed rendering service in its host application.


Open up any project. V-Ray for Swarm can be opened in two different ways.  The first is by clicking on the Render drop-down to access the Swarm button to enable Swarm. Secondly, you click the V-Ray tab and go to the Settings icon in the toolbar. Click V-Ray Swarm Enabled and you’ll see the Swarm settings. 




Click Refresh to see the tags for the machines that are currently running. Click the tags to enable or disable them so that your Swarm render distributes only to the machines with that tag. Selecting two or more tags will distribute to machines that have at least one of the selected tags. This can be done while rendering.




Click on the Render drop-down to access the Swarm button to enable Swarm. 



The Swarm button is a quick button. If the Swarm Settings have been adjusted either during the installation of V-Ray for Revit or adjusted in the Swarm settings from the Settings dialog, next time Swarm needs to be used, you can do it in one click using the Swarm button.


Now click Render With V-Ray icon to start this rendering. V-Ray will first calculate secondary Illumination, so you won’t be able to have a visual representation of the other machines jumping in to help this render until V-Ray gets to rendering the buckets. 


In the V-Ray Rendering Progress dialog, click on the Distributed Rendering arrow to expand it. This bar shows how many machines are being used. If you slide the Goal slider to the right, you can dynamically add more machines to this render.




The system will have to send project files to the render node, so it takes a moment for the transfer. As soon as it completes the transfer, you can see a slew of new buckets appear on the image that is being processed by the other Swarm machines.

The green marker displays what part of all available machines are rendering the job. Node and CPU information is displayed upon in the Current usage bar. In case some of the machines are busy/unavailable, a marker in beige will display on the opposite side of the green one, showing their amount. 

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




The V-Ray Swarm button opens up the V-Ray Swarm web interface. Alternatively, it can be accessed by typing in the IP address of the current Master Node machine on the default port 24267.
