Fusion Nodes is an addon for Blender that gives you access to the same shaders used in Blackmagic Fusion, available directly within your Blender node setups. It ships with nine nodes to choose from, covering a range of shading models for building realistic renders.
The included nodes are the Class Shader, Master Shader, Reflect Shader, CTR Shader, Cook Torrance, GP/PB Shader, Olympic Shader, Phong Shader and WARD Shader. Once installed, the new nodes become available for use in your existing node graphs, fitting into the workflow you already have.
Documentation is provided with the addon. It is published under the GPL license and supports a broad span of Blender releases, from 2.91 through 3.4, making it suitable for both experienced 3D artists and those getting started with shading in Blender.
