Unity ShaderLab 实现网格爆炸

实现思路：

沿着3D物体每个面的法线，将面偏移一定的位置。

Shader Graph实现如下：

Shader Lab 实现如下：

Shader "Unlit/MeshExplode"
{Properties{_MainTex ("Texture", 2D) = "white" {}_Distance("Distance",Float) = 0}SubShader{Tags { "RenderType"="Opaque" }Pass{CGPROGRAM#pragma vertex vert#pragma fragment frag#include "UnityCG.cginc"struct appdata{float4 vertex : POSITION;float4 normal : Normal;float2 uv : TEXCOORD0;};struct v2f{float2 uv : TEXCOORD0;float4 vertex : SV_POSITION;};sampler2D _MainTex;float4 _MainTex_ST;float _Distance;v2f vert (appdata v){v2f o;o.vertex = UnityObjectToClipPos(v.vertex + v.normal * clamp(_Distance,0,100) * 0.01);o.uv = TRANSFORM_TEX(v.uv, _MainTex);return o;}fixed4 frag (v2f i) : SV_Target{// sample the texturefixed4 col = tex2D(_MainTex, i.uv);return col;}ENDCG}}
}

实现效果如下：
