关于修改材质的RenderingMode的两种方式

有时百度搜不了 要去谷歌想一些英文来搜才行
下面是我辛苦搜集的结果， 有需要的朋友可以参考。
第一种

public static void SetMaterialRenderingMode(Material material, RenderingMode renderingMode)
	{
		switch (renderingMode)
		{
			case RenderingMode.Opaque:
				material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
				material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);
				material.SetInt("_ZWrite", 1);
				material.DisableKeyword("_ALPHATEST_ON");
				material.DisableKeyword("_ALPHABLEND_ON");
				material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
				material.renderQueue = -1;
				break;
			case RenderingMode.Cutout:
				material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
				material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.Zero);
				material.SetInt("_ZWrite", 1);
				material.EnableKeyword("_ALPHATEST_ON");
				material.DisableKeyword("_ALPHABLEND_ON");
				material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
				material.renderQueue = 2450;
				break;
			case RenderingMode.Fade:
				material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.SrcAlpha);
				material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
				material.SetInt("_ZWrite", 0);
				material.DisableKeyword("_ALPHATEST_ON");
				material.EnableKeyword("_ALPHABLEND_ON");
				material.DisableKeyword("_ALPHAPREMULTIPLY_ON");
				material.renderQueue = 3000;
				break;
			case RenderingMode.Transparent:
				material.SetInt("_SrcBlend", (int)UnityEngine.Rendering.BlendMode.One);
				material.SetInt("_DstBlend", (int)UnityEngine.Rendering.BlendMode.OneMinusSrcAlpha);
				material.SetInt("_ZWrite", 0);
				material.DisableKeyword("_ALPHATEST_ON");
				material.DisableKeyword("_ALPHABLEND_ON");
				material.EnableKeyword("_ALPHAPREMULTIPLY_ON");
				material.renderQueue = 3000;
				break;
		}
	}

第二种

材质上面 的 renderingMode     0 opaque  2 fade 
material.SetFloat("_Mode", 2.0f);
