BSDFPreview Basic Inputs Outputs Context
This Node is automatically included when a Node Material is created and it defines the reflective properties of a surface. By default the BSDF will compute indirect illumination in the form of diffuse reflections. While very realistic, this effect can often be too expensive to compute within a reasonable time frame, especially for interior scenes. To remedy this, you can enable the "Use Color Channel for Node Material” option: Then the BSDF will be setup to work with the Global Illumination effect in the Render Settings.
