JavaScript => public function SetOverrideTag(tag: string, val: string): void;
C# => public void SetOverrideTag(string tag, string val);

Parameters 参数

tag	Name of the tag to set. 设置标签的名称。
val	Name of the value to set. Empty string to clear the override flag. 设置值的名称。

Description 描述

Sets an override tag/value on the material.

设置该材质的重写标签。

Will set a tag/value on the material that overrides the value of said tag from the shader. This can be used to make sure replacement shaders (such as rendering DepthNormals) work even if the original shader only supports a certain render type. For example if a shader only supports a specific render type but renders in many ways using keywords, SetOverrideTag can be used fom a custom material inspector to ensure that the material renders correctly even if the shader is replaced.

这个会设置该材质的一个标签，从shader重写标签表示的值。这用来确保替换shader（如渲染深度法线），即使原始shader仅支持某一渲染类型。例如，如果shader仅支持一个指定的渲染类型，但使用关键词渲染多种方法，SetOverrideTag 能使用自定义的材质检视面板来确保材质正确渲染，即使shader被替换。

JavaScript:

#pragma strict
private var material: Material;
public function SetupBlendMode(blendMode: BlendMode) {
	switch (blendMode) {
		case BlendMode.Opaque:
			material.SetOverrideTag("RenderType", "");
 
			material.DisableKeyword("_ALPHATEST_ON");
 
			material.renderQueue = -1;
 
			break;
		case BlendMode.Cutout:
			material.SetOverrideTag("RenderType", "TransparentCutout");
 
			material.EnableKeyword("_ALPHATEST_ON");
 
			material.renderQueue = 2450;
 
			break;
	}
}

C#:

public class ExampleClass : MonoBehaviour
{
	private Material material;
 
	public void SetupBlendMode(BlendMode blendMode)
	{
		switch (blendMode)
		{
			case BlendMode.Opaque:
				material.SetOverrideTag("RenderType", "");
				material.DisableKeyword("_ALPHATEST_ON");
				material.renderQueue = -1;
				break;
			case BlendMode.Cutout:
				material.SetOverrideTag("RenderType", "TransparentCutout");
				material.EnableKeyword("_ALPHATEST_ON");
				material.renderQueue = 2450;
				break;
		}
	}
}
