ASE实例1-熔岩效果

一个入门级的UV移动+材质叠加+Sin时间，形成的熔岩明暗交替流动效果
要点：
1.TextureCoordinates，纹理坐标，代码为UV=UV * 缩放+ 偏移，控制UV的缩放和偏移
2.Panner节点，UV控制器，代码为UV=UV+Speed.xy*Time，常用于UV随着时间发生变化

生成代码：

		_Albedo("Albedo", 2D) = "white" {}
		_Normals("Normals", 2D) = "bump" {}

		_Specular("Specular", 2D) = "white" {}
		_TileableFire("TileableFire", 2D) = "white" {}
		_FireIntensity("FireIntensity", Range( 0 , 2)) = 0
