VRay for SketchUp Manual

Distributed Rendering

Distributed Rendering is the capability to render a single image across multiple computers. This has the possibility of utilizing multiple computers which can greatly increase rendering speed. VRay can use up to ten computers with just one license.

In order for V-Ray to utilize these extra machines there are two things that need to be done. First, there needs to be a way for V-Ray to actually use the other machine. Secondly, V-Ray needs to be told to look for those machines.

Setting Up the V-Ray Distributed Rendering Spawner

The way in which V-Ray communicates with other computers (known as the slave machines) is through a stand alone application which is installed and run on the slaves. Any machine which has V-Ray for SketchUp installed on it should have the Distributed Render Spawner already on the machine. If it does not, or you would like to install the DR Spawner that does not have V-Ray for SketchUp you will need to access your installation file or disk. Once the installation is started you will need to choose Custom setup type. Within the custom setup there will be four components, one of them being the DR Spawner. Disable all of the other components and click next to install the DR Spawner.

Setting Up the V-Ray Distributed Rendering Spawner

Finding the IP address of the slave computer

The last piece of information that you will need in order to utilize the slave machine is the IP address. You can get this one of two ways. The first is to go to Network and Internet Connections in the Control Panel. From there double click on Network Connections. This will bring you to a window containing all of your internet connections. Double click on the connection you intend to connect through and that will bring up dialog box containing the status of that connection. At the top, click on the second tab labeled Support. Take note of the IP address as you will need this information in a few moments.

The second way of retrieving your IP address is to use the run command. You can get this by going to the start menu and clicking on Run. Now type IPCONFIG which will tell you the IP address of you machine. If your computer only flashes the result, than you can type CMD.EXE into the Run window and then IPCONFIG in the resulting DOS interface.

Finding the IP address of the slave computer

Starting the DR Spawner

Once the DR Spawner is installed on the slave machine you will need to start the application. In the folder C:\Documents and Settings\All Users\Application Data\ASGvis you will find a folder called DRSpawner. Open that folder and you will find the DR Spawner. Double clicking on the DR Spawner will launch it, and once it has successfully loaded the Spawner it is ready to go.

Starting the DR Spawner

Connecting to Slave Machines

Now that the slave machines are ready to go we need to tell the main computer where to render from, also known as the client, not only that, we will be using other computers to render but also how to access them. This is very simple as well. Within the Systems rollout of V-Ray's options you will see a checkbox and button for Distributed Rendering. To enable Distributed Rendering simply click the checkbox next to the button. Clicking on the button will bring up a window which will allow you to input the IP addresses of any slave machines you wish to use. Within the Distributed Rendering window at the top you will notice the option to Add a Server. This is where you will input the IP addresses of any machines that you will connect to. After you input any IP addresses you will want to click Resolve servers.

Connecting to Slave Machines

Some Considerations For Distributed Rendering

With using Distributed Rendering you might run into several possible issues. When trying to connect to slave machines you may have issues of not actually getting them to render. Check any firewalls that may be on the host or slave machine as well as any routers that you may have. Also, textures will not be transferred to the host machine by the DR software. Optimally, textures should be in a single network location that is accessible to all machines being used, but if this is not possible then you must manually transfer the textures manually to a folder on the slave machine(s) that is the same path as on the host machine. Also, if you have the capability to use Remote Desktop Connection or a similar software, it may make the task of monitoring slave machines an easier task.
