Understand sky

You can create the following types of sky if your project use the High Definition Render Pipeline (HDRP):

• Physically based sky
• High dynamic range imaging (HDRI) sky, which is a simple sky that uses a cubemap texture.
• Gradient sky, which is a simple sky where HDRP interpolates between three colors.
• Custom sky effects

Use a Visual Environment Volume Override to change the type of sky HDRP uses, and configure the sky and clouds.
