Cluster

Video captions: In VRED, an image computation process can be shared by multiple computers with the help of clusters. This means, internally, the image is split and sent to different computers for computation. Enable cluster rendering, via the Rendering menu, and select Cluster. Under Mode, you can select the cluster mode. Choose Raytracing. To be able to connect to different computers, you have to enter the IP addresses or hostnames for the PCs in the Servers field. For all computers you want to cluster with you will need an install cluster service or an installed version of VRED Professional. With a slow network connection, it is recommended to choose Low (Lossless) under Compression so the performance of the rendering in the interactive clustering isn’t slowed down by bandwidth. Start the connection to your cluster through the selection of Start Cluster. Open the statistics of your scene by selecting Statistics. Under Number of cores, the number of the now available cores is being displayed. Open the Windows Task Manager to get an overview of your running processes. Double the amount of working memory is needed for the scene as it has been loaded into the cluster. As you can also see, a new VRED cluster service has been started. The complete processing effort happens in the VRED Cluster Service and not in VRED Professional itself. Open the Render Settings, via the Quick Access Bar. Set the path to which the rendering is saved and run Render. As you can see, the Cluster Snapshot window opens itself up. Via Update Preview, you can view the progression of the rendering, and with the help of the left mouse button, inspect it at render size. By selecting Save and Cancel, you can save the current state of the progress on the rendering and then abort it.
