Rendering Pass Specifies the rendering pass that HDRP processes this material in.
• Before Refraction: Draws the GameObject before the refraction pass. This means that HDRP includes this Material when it processes refraction. To expose this option, select Transparent from the Surface Type drop-down.
• Default: Draws the GameObject in the default opaque or transparent rendering pass pass, depending on the Surface Type.
• Low Resolution: Draws the GameObject in half resolution after the Default pass.
• After post-process: For Unlit Materials only. Draws the GameObject after all post-processing effects.
