Material Validator in the Built-In Render Pipeline
Understand how the Material Validator can help you make sure materials use values that fall within the recommended range for physically-based shaders.
Read time 1 minuteLast updated a month ago
The Physically Based Rendering Material Validator is a draw mode in the Scene View. It allows you to make sure your materials use values which fall within the recommended reference values for physically-based shaders. If pixel values in a particular material fall outside of the reference ranges, the Material Validator highlights the pixels in different colors to indicate failure.
Also note: The validator only works in Linear color space. Physically Based Rendering is not intended for use with Gamma color space, so if you are using Physically Based Rendering and the PBR Material Validator, you should also be using Linear color space.
Open the Material Validator
To use the Material Validator, select the Scene View’s draw mode drop-down menu, which is is usually set to Shaded by default.

Navigate to the Material Validation section. The Material Validator has two modes: Validate Albedo and Validate Metal Specular.
