ProceduralMaterial.GetProceduralPropertyDescriptions 获取程序材质属性描述数组

function GetProceduralPropertyDescriptions () : ProceduralPropertyDescription[]

Description描述

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

获取这个程序材质所有属性描述的一个数组。

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.

这可以用来构建泛型GUI,能用来编辑任意程序材质的属性,而事先不知道它的属性。
