Quick Overview

A Render Farm consists of a group of networked computers working together to complete large rendering tasks. Render farms proceed silently, without graphically displaying the renderings as they progress, or you can run the Render Farm Display tool to display parts of the image as they are completed. Using the Render Farm allows you to use more compute power for lengthy tasks at the expense of some interactivity. The IRender nXt Render Farm Software is sold separately from IRender nXt itself. (Hhowever a 2-CPU Render Farm is included with the Combo Pack). Also A 30-day 2-CPU trial is available for testing. Neither SketchUp nor IRender nXt itself are required on computers which will only be used for rendering farming.



Manufacturer Part Number: RNF200


The nXt Render Farm includes four pieces of software:

  1. IRender nXt is used to define the model to render. The Render Farm can be started directly from IRender nXt, or if you prefer to preview the rendering first you can start a preview rendering (with smaller resolution and fewer passes), and then start the Farm from IRender Batch.
  2. The Farm itself, (nXt.exe ornXt64.exe, runnning on each Farm CPU). This is a version of the nXt rendering engine which renders nearly silently, in the background, with very little user interface. This portion of the nXt Render Farm Software can be used by itself, in conjunction with commercial render farm software, for a more sophisticated render farm solution.
  3. nXtFarmer.exe (nXtFarmer64.exe) is a small executable that runs on each network rendering station, waits for jobs to be generated, and starts the Farm Processor.
  4. IRenderBatch.exe is a utility program to display renderings as they are completed and save them as .JPG, .PNG or .ArImage files.


You can download the IRender nXt Render Farm software from the McNeel nXt Forum:

Be sure to download the version to match your operating system (32 bit or 64 bit)

Installing and Configuring the Render Farm

Create a shared folder for use by the render farm. (Create a folder on a machine which is accessable by all the other machines which will process or use the Render Farm)

All of the network rendering computers must have read/write access to this folder. The shared folder should have a lot of available disk space to store both data (input) and images (output.) 20 - 200 GB of available storage are recommended. You must perform the following four steps on each computer you plan to use in the render farm, including any nXt workstations which will submit jobs to the render farm:

  1. Install the nXt Render Farm Software.
  2. From the Start menu, run the Render Farmer on each machine. The Render Farmer will appear as an icon in the system tray.
  3. Right click on the icon and select Restore. A window title nXt Farmer should appear.
  4. Select Options?Path from the menu and select the path to the render farm. The Farmer window can now be minimized to the tray.

The Render Farm is now configured. To verify that the farmer machines are responding run the Render Farm Monitor from the Start menu on any of the workstations. The machines should appear in the Configure Machines window. If you wish to exclude a machine from participating in the render farm, you can select it, right click, and choose Suspend.

Submitting a Job to the Render Farm

There are two modes to start a Render Farm job:

  1. Start the Farm directly from SketchUp, or
  2. Do a preview render first, and start the Farm from IRenderBatch.

Submitting a Farm job directly from SketchUp

Perform the following steps to submit a job to the render farm:

  1. Configure your model and rendering parameters in the usual way.
  2. Press the Farm button on the toolbar to show Render Farm parameters.
  3. Choose to either run the job Start Now, Manual, or Start at Specified Time. If you choose Manual' you will need to use the nXt Render Farm Monitor to manually start the job. See: Setup below.
  4. Maximum Tasks to Farm Out determines how many sub-tasks to slice the job into. See: [#Setup|Setup]] below.

After the job is complete, output can be found in the job's Output folder.

Preview the rendering first

  1. Start your rendering normally from SketchUp. (Perhaps at a smaller resolution or with fewer passes)
  2. Examine the rendering. Make changes to materials, settings, etc. if desired
  3. Use Farm Icon to start the Farm from IRender Batch.
