+New Materials in HDRP use the [Lit Shader](Lit-Shader.md) by default. To create an AxF Material from scratch, create a Material and then make it use the AxF Shader. To do this:
 
 1. In the Unity Editor, navigate to your Project's Asset window.
 2. Right-click the Asset Window and select **Create > Material**. This adds a new Material to your Unity Project’s Asset folder.

 | **- Enable Refraction** | Indicates whether the clear coat is refractive. If you enable this checkbox, HDRP uses angles refracted by the clear coat to evaluate the undercoat of the Material surface. |
 | **- - Clearcoat IOR**   | Specifies a Texture (red channel only) that implicitly defines the index of refraction (IOR) for the clear coat by encoding it to a monochromatic (single value) F0 (aka as specular color or Fresnel reflectance at 0 degree incidence. This also assumes the coat interfaces with air). As such, the value is in the range of **0** to **1** and HDRP calculates the final IOR as:<br/>`IOR =  (1.0 + squareRoot(R) ) / (1.0 - squareRoot(R))`<br/>Where **R** is the normalized value in the red color channel of this Texture.  Note: HDRP uses this IOR for both coat refraction and, if enabled, transmission and reflectance calculations through and on the coat. Therefore, you must always assign a Texture to this property when you enable clear coat. |
