扰动

直接对uv进行变换就可以了，记得首先把六边形格子地图的Tilling调高点 先预先调成合适大小的六边形，然后repeat铺满整个护盾

// Tiles and offsets the value of input UV by the inputs Tiling and Offset respectively.
// This is commonly used for detail maps and scrolling textures over Time.
void Unity_TilingAndOffset_float(float2 UV, float2 Tiling, float2 Offset, out float2 Out)
{
    Out = UV * Tiling + Offset;
}

直接在vertex着色器中对appdata传进来的uv进行变动，两者 offset的变动频率不同

            v2f vert (appdata v)
            {
                v2f o;
                o.vertex = UnityObjectToClipPos(v.vertex);
                half2 uv = TRANSFORM_TEX(v.uv, _MainTex);
                Unity_TilingAndOffset_float(uv, half2(1, 1), half2(0, -_Time.y), o.uv);
                Unity_TilingAndOffset_float(uv, half2(1, 1), half2(0, -_Time.y * 2), o.uvGlow);
                
                float3 worldPos = mul(unity_ObjectToWorld, v.vertex).xyz; 
		
                o.worldViewDir = normalize(UnityWorldSpaceViewDir(worldPos));
			    o.worldNormal = UnityObjectToWorldNormal(v.normal);
                return o;
            }

            {
                v2f o;
                o.vertex = UnityObjectToClipPos(v.vertex);
				...                
                float3 worldPos = mul(unity_ObjectToWorld, v.vertex).xyz; 
		
                o.worldViewDir = normalize(UnityWorldSpaceViewDir(worldPos));
			    o.worldNormal = UnityObjectToWorldNormal(v.normal);
                ...
                    
                return o;
            }

fragment着色器

先获取世界坐标系下的法线向量和世界坐标系下摄像机到顶点的向量，1-点乘得到的值然后结合到最后的颜色输出计算中，法线向量与摄像机到顶点的向量的所成夹角可视为从中心点向边缘扩散，角度越来越大，到边缘区角度呈局部最大值

            half4 frag (v2f i) : SV_Target
            {
				...
                half rim = pow(1 - abs(dot(normalize(i.worldNormal), normalize(i.worldViewDir))), _RimNum);

                // 边缘高光
                col = lerp(col, _LightColor, rim);
                ...

                return col;
            }

最后大功告成了，后续可能会继续改进一下（加上相交时会留下边缘光）
