Skybox Shaders

Unity provides multiple Skybox Shaders for you to use. Each Shader uses a different set of properties and generation techniques. Each Shader falls into one of the following two categories:

Render pipeline compatibility

The Built-in Render Pipeline, and the Universal Render Pipeline (URP) both exclusively use skyboxes to render a sky. They both support all of the above Shaders.

The High Definition Render Pipeline (HDRP) does not support any of the above Shaders and instead includes multiple sky generation solutions.
