								1.ctrl + a 选中 Alpha1. 按 ctrl + c 复制。

								2.ctrl + a 选中 红通道。ctrl + v 粘贴将其覆盖。绿，蓝通道执行同样的操作。

								3.删除Alpha 1 透明通道保存.

								需要改进 => 1.缺少 panel clip shader 
											2.流程脚本化

CullBlack 核心代码:


	sampler2D _MainTex;

	fixed4 frag(v2f IN) : SV_Target
	{
		fixed4 col = tex2D(_MainTex, IN.texcoord);

		//黑色像素透明度为0
		if(col.r >= 0 && col.r <= 0.07 && col.g >= 0 && col.g <= 0.07 && col.b >= 0 && col.b <= 0.07 )
		{
			col.a = 0;
		}

		return col;
	}
