Set up distributed rendering in V-Ray to offload the work to our dedicated render servers. This will decrease the time it takes to finish a render. The servers run a network rendering program called DRspawner. There is no batch rendering or render queue when using V-Ray. If the server is busy rendering another job, it will default back to rendering on your computer.

The following information describes how to setup V-Ray for network rendering.

NOTE: you need to be on the campus network for this to work

  • On Rhino’s menu, click V-Ray > Options, then click System

Under the Distributed Rendering section:

  • Place a checkmark next to “On” and “Asset Collection”
  • Set Mode to “Send to each node”
  • Click the Hosts … button
  • Click Add server
  • For host name enter arch-render-1.syr.edu
  • Click Resolve servers. It should fill in an IP address. If not, make sure you spelled the server name correctly.
  • Add the second server arch-render-2.syr.edu and again click Resolve servers
  • IMPORTANT: place a check mark in the box to the left of each server
  • Click OK to close the render settings windows

Renderings will now be done on the servers instead of on your computer. The render progress window will show something similar to ‘Server 128.230.2.212: Starting frame 0’ and/or ‘Server 128.230.2.213: Starting frame 0’ at some point.

Textures and materials are automatically sent by your computer to the server as long as they are available on your computer.

If the servers are busy rending other V-Ray jobs, your computer will default back to running the render locally.

You must keep the V-Ray render progress window open during the rendering process.

If you get black squares on your output window and the render is done, you may want to try again.
