![]() Just open and click render (be sure to render at the right resolution) I used that scene over the years to estimate the rendering performances of my hardware. Here you can download for free an effective Maya/Mental Ray Benchmark scene. Network Rendering may be of greater benefit also if you are working from a laptop computer where your computer is significantly slower than the network nodes, and this makes up for the lags inherent in network overhead. Simple jobs do not pose much benefit because of the overhead of communicating over the network to control the job. It is our experience that only the most complex of rendering jobs will render faster on the network. This may seem counterintuitive, but in some cases, depending on complexity and file size, rendering just locally will be faster than processing on the network. During a render, messages similar to the following are output to the Output Window:ġ) Mental Ray Satellite network rendering does not have a queue.Ģ) Network Rendering in Mental Ray Satellite may or may not be faster than rendering on your local machine only. Set the verbosity level for messages from the translation process by using the MEL command as outlined in Export Verbosity. To verify which hosts file is being read when you are rendering: Each node on the render farm is working on up to 8 buckets (4 physical cores 4 Hyper treading) at a time with my i7 machines. Within a few moments you should see the render process begin, with various square “buckets” (or portions of the image) beginning to populate the rendered image. The job may take a moment to start, as your computer sends the Maya file, all textures, and other information up to the render nodes and kicks of the process. Using this, your machine will be rendering and the network will be rendering, adding your machine as a node in the farm process. to ready the scene for rendering.ģ) Choose Render > Render Current Frame > click the box next to render current frame to get to the settingsĤ) Check Render on Network Machines Checkbox to use the network.ĥ) Optionally, Render on Local Machine (your own current session of Maya) also. Network rendering only works under Mental Ray.Ģ) Setup all rendering setups, lights, etc. NOTE: It is highly advised to check the exact PORT NUMBER in "C:\Windows\System32\drivers\etc\services", you should find a string like "mi-raysat2013 7413/tcp" or something.ġ) Under Render Settings, choose Mental Ray as your renderer. You can use IP addresses as well as machine names. The port number set on mental ray for Maya Satellite slave machines is, usually, 7413. These slave machines must be accessible on the network where mental ray for Maya (the master machine) is installed.įor mental ray for Maya Satellite masters, you must add the port number by typing “:port number” after the hostname in the maya.rayhosts file. The maya.rayhosts file must contain a listing of each slave machine’s name. Mental Ray satellite will start automatically as windows service.ġ)Create a user in all your windows OS (master and slaves), make it administrator.Ģ)Create a file called maya.rayhosts in "\Users\username\Documents\maya\2013\prefs" directory. Once you finishd the installation reboot your systems. Be sure to download the same version of your Maya in use. You could be tempted to think that Mental Ray for Maya distributed network rendering is something like backburner, a job scheduler good for batch renders like final renders or animations frames.well it's not! Mental ray's distributed rendering is awesome, because it's automatic (you just have to configure once in your life and it will always work as you launch Maya) and it works not only in batch render but in preview and IPR renders too, either along side the local computer or without it, freeing the local computer to continue working.įirst of all you need to install Mental Ray Satellites to all your maya's slaves. Anyway when you work on high-res renders you can take a great advantage of distributed rendering in Mental Ray. You should know that not any kind of render operation is parallelizable, for the truth a lot are still single core compiled (like hair and fur generation). You can find more information to the official Mental Ray Nvidia website website.Īutodesk Maya comes with 3 node licences, in theory it means a speed up performance of 300%, in pratics it's 190% with 1 master and 1 slave, and its 250% with 1 master and 2 slaves when we are working in a multi-core optimized scene. Since Mental Ray 2017 this guide is obsolete, now there's a new simple method to do distributed render in Mental Ray but you need a MR license to make it work.
