今天写shader流光效果，shader代码少了个括号，unity shader compiler卡死且不提示原因

 

好在找到了原因，shader 代码如下，原理是提高经过的颜色亮度

 

void surf(Input IN, inout SurfaceOutputStandard o) {
			// Albedo comes from a texture tinted by color
 
			fixed2 scrolledUV = IN.uv_MainTex;
 
 
			fixed xScrollValue = 5 * _Time;
			fixed yScrollValue = 5 * _Time;
 
			scrolledUV += fixed2(xScrollValue, 0);
 
			fixed4 c = tex2D(_MainTex, IN.uv_MainTex);// *_Color;
 
			fixed4 d = tex2D(_FlowTex, scrolledUV);
 
			//if (d.a == 1) {
			if(d.a > 0.5) {
 
				o.Albedo = c.rgb;
			}
			else {
 
				o.Albedo = c.rgb + float3(d.a,d.a,d.a);
				
			}
			// Metallic and smoothness come from slider variables
			o.Metallic = _Metallic;
			o.Smoothness = _Glossiness;
			o.Alpha = c.a;
		}
