If you are a Blender-only license holder and have a small render farm of your own, you will need an additional Render Node license for each extra machine you want to use for rendering. For larger setups, typically with ten or more machines, Render Node packages are the most cost-efficient option.
If you have multiple V-Ray Solo, Premium, or V-Ray Collection licenses, you can use those across your machines.
Alternatively, you can render through one of our certified render farm partners or use Chaos Cloud, our cloud-based rendering service.
