ProceduralMaterial.GetProceduralPropertyDescriptions

function GetProceduralPropertyDescriptions () : ProceduralPropertyDescription[]

Description

Get an array of descriptions of all the properties this Procedural Material has.

This can be used to build generic GUI that can be used to edit the properties of any Procedural Material without knowing the properties of it in advance.
