Unity Shader Graph(二)Dissolve Effect

此篇文章记录Dissolve Effect(溶解特效)的制作过程

软件环境

Unity 2018.1.2f1

Packages: Lightweight Render Pipeline 1.1.11

Dissolve Effect最终效果

创建工程及初始设定

New Project & New Scene;

创建Lightweight Pipeline Asset,打开Vertex Lighting与HDR,关联到Graphics Settings当中;

在场景中放置Monkey Model,创建默认材质Default,Albedo = (25, 25, 25, 0)

摄像机Clear Flags设置为Solid Color = (80, 80, 80, 0), FOV = 40;

Player Settings的Color Space = Linear;

初始设定预览

溶解特效

使用Simple Noise结点生成随机Alpha贴图,AlphaClipThreshold与Alpha一起控制片段的显示或隐藏:当片段的Alpha < AlphaClipThreshold时,此片段将被丢弃,即隐藏不显示出来。

溶解边缘发光特效

使用Step结点将Alpha贴图转换为黑白分明的贴图,黑白贴图与Color相乘后输入到Emission;

Step Node: Returns 1 if the value of input In is greater than or equal to the value of input Edge, otherwise returns 0.

Post Processing Effects

选中Main Camera,添加组件Post Process Layer(Layer = PostPorcessing);

Post Process Layer

创建Post-process Volume(GameObject -> 3D Object -> Post-process Volume),设置Layer = PostProcessing,Blend Distance = 1。调整Volume大小,将Monkey Model包含在内部;

Post-process Volume

新建Post-processing Profile:

  a) Add effect: Color Grading(Mode = ACES)

  b) Add effect: Bloom(Intensity = 2, Threshold = 1)

添加后期处理特效后,最终效果如下图
