Rendering computer-generated imagery (CGI) is often the most demanding phase of any 3D project. Whether working on detailed animations, high-resolution architectural visualizations, or intricate rendering tasks, the process requires a lot of processing power. For many 3D artists, rendering is a bottleneck, as even the most advanced 3D rendering software can only do so much on a single machine. Some projects may take hours to render a single frame or even months to render an entire animation.
The purpose of a render farm is to solve this problem. A render farm consists of many render nodes working together to speed up the rendering process and eliminate delays. By distributing rendering tasks across multiple machines, render farms provide the rendering power needed to complete even the most ambitious projects efficiently.
Rendering high-resolution CGI takes more than just artistic talent; it demands significant computational resources. When a project becomes more complex, such as with feature animations or detailed simulations, rendering speed often drops dramatically. It’s not uncommon for larger rendering projects to take weeks or months to finish without additional support.
Using a render farm can reduce rendering time significantly, making it possible to deliver results faster while freeing up your local workstation for other tasks. Many render farm providers offer solutions that are scalable and designed for rendering projects of all sizes. Whether you need GPU rendering, CPU rendering, or both, render farms provide the necessary resources to complete the rendering process without strife.
A render farm works by distributing rendering tasks across many render nodes, each dedicated to rendering a portion of the project. Render farm software orchestrates the rendering process and eliminates bottlenecks by allocating tasks to render nodes based on their availability and processing power. For instance, instead of one workstation taking 10 days to render a project, a render farm can shrink that time to just hours.
When you upload a project to a render farm, the software ensures all textures, simulations, and dependencies are linked correctly. By managing these details seamlessly, the render farm makes rendering high-resolution CGI practical for individual artists and studios alike. Larger render farms often consist of hundreds—or even thousands—of render nodes, which work together to speed up the rendering process exponentially.
Render farms come in different configurations, tailored to the needs of artists and studios. Among the most popular are commercial cloud render farms, which are scalable and available for rendering whenever needed. Using cloud render farms allows you to upload your project to a render farm provider and access powerful computing resources on demand.
On-site render farms, on the other hand, consist of self-built render nodes located within a studio. Building an on-site render farm may require a significant upfront investment, but it offers complete control over the rendering process. On-site render farms also ensure your projects remain in-house, which can be an important consideration for some studios.
Traditional render farms or community-based setups rely on shared hardware contributed by users. While affordable, they may not match the rendering speed or reliability of commercial render farms, especially for rendering high-resolution tasks. Different types of render farms cater to various render needs, making it crucial to choose the right option based on your project requirements.
The following infographic broadly illustrates a typical cloud render farm pipeline. First, a user’s project and its dependencies are collated, relinked, and uploaded to a render farm file server via DCC plugins. Once on the File Server, the project is usually already configured to read assets from the directory created for it by the farm. When the render job is launched, multiple render nodes open the project and render the assigned frames on the render software intended and according to the specifications set by the user in their project and on the settings for the render job prior to launching it. Once completed, the rendered output is sent back to the file server, where it becomes available for download to the user’s local computer. The frames are then sent to a Compositor or Video Sequencer for Post work before the final render of the animation in a video format.

Render farms are dedicated to rendering tasks that would otherwise tie up individual workstations for days. Their primary advantage is the ability to speed up the rendering process, ensuring projects are completed on time. Many render farm services allow artists to work on multiple tasks simultaneously, as the farm handles the heavy lifting of rendering.
Using a commercial render farm also enables higher-quality results. Artists can leverage the rendering power of many render nodes instead of relying on a single machine. This capability allows for advanced rendering settings, such as intricate lighting setups, higher texel density, and ultra-detailed textures, which enhance the final render.
Render farm costs can vary, but they often prove cost-effective by reducing downtime and enabling studios to take on more projects. Flexible pricing models make it easy to balance rendering speed with budget considerations, especially when working with a cloud-based farm service.
Renderly is a 3D artist and Youtuber who shares his perspective on the use of a render farm, and our service in particular.
Using a render farm effectively requires careful planning. For studios with heavy rendering needs, an in-house farm might seem appealing, but the upkeep—hardware maintenance, energy consumption, and constant upgrades—can become a logistical nightmare. Online render farms, by contrast, remove these headaches, offering scalable solutions tailored to your project’s needs.
Budgeting for a render farm involves more than just estimating rendering costs. Factor in potential testing sessions to identify issues before committing to a full render. Render farms handle projects efficiently, but they can’t compensate for problems baked into the files you upload. Missing dependencies, incorrect lighting setups, or unoptimized assets can lead to wasted time and money if caught too late.
User-end testing is crucial. Render a few frames locally to ensure everything is working as expected. Make a few test renders on the render farm and compare results to avoid surprises during the final render. For online farms, understanding your project’s deadline and priority level can also help you choose the right service tier, balancing cost and speed. If an online render farm offers support, relay any questions or concerns to the support team before starting a render to ensure that your rendering experience is smooth and without problems.

Even though modern 3d software is much more intuitive, allows for faster creation and can handle more complex scenes, optimizing your scenes at the production level is still very important even if you plan to use a render farm with powerful hardware, as any unnecessary render time equates to an increase in cost.
Yak of Art shares some optimization techniques in his video:
Ultimately, preparation is your best ally. A well-planned render minimizes errors, maximizes efficiency, and ensures every dollar spent on the farm delivers value.
Whether you’re using a self-built render farm, a cloud render farm, or a traditional setup, understanding your project’s requirements is key. On-site render farm setups may suit studios with ongoing rendering needs, while cloud render farms offer flexibility for occasional large-scale rendering tasks.
