Getting "Surface Options" in Custom GUI in URP 12.0+

How does one get the "Material Override" surface options to show up in a custom GUI that inherits from "ShaderGUI".

I'm at a complete loss as I cannot find any references to this online.

 

Hey, I have the same problem so I wonder if you found a nice solution.

I'm trying to use a custom GUI with a Shader Graph material, and the closest I could find is that you can write by hand all these options (surface type, render face, etc..) in the custom GUI script using the properties references that you see in the shader graph inspector (orange frame on my screenshot).
Edit : I forgot to mention you have to check "allow material override" to see and access those properties
The problem here is that they all appear as floats, and so you have to find yourself which value equals which mode

 

Having the same problem here
I'm rewriting everything by hand for now, with some help from the built-in shader source files (StandardShaderGUI.cs)

 

try BaseShaderGUI
