# Worker node It is where the actual rendering takes place. Each Worker Node is equipped with a tool called the Render Engine Controller, along with one or several render software or render engines, such as Blender Cycles, V-Ray, Keyshot, D5 Render, Octane, etc. See the [rendering flow](https://docs.inferix.io/inferix-whitepaper/decentralized-visual-computing/pages/Di2djAZNb70Mcrxp34yf##fig_rendering_flow) for more details. The render engines utilized by Worker Nodes typically rely on path-tracing/ray-tracing techniques, which demand substantial compute resources. Some of these engines are open-source and free, such as Cycles, while others, like V-Ray, are paid software. If there are any render engine costs, they will be factored into the rendering price that the Inferix network charges users. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
