插入函数
光照模型
顶点和最终颜色修改
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#pragma surface surf Mao fullforwardshadows vertex:vert finalcolor:final //重要定义中的最后两个就是设定两个函数
。。。。。。
voidvert(inout appdata_full v) { }

插入位置
以新建的SurfaceShader为标准，顶点修改和最终颜色插入到它下面，自定义光照模型在它上面

//大致上要将顶点修改和最终颜色修改加入到这个位置

halfasview Pass half-direction vector into the lighting function instead of view-direction. Half-direction will be computed and normalized per vertex. This is faster, but not entirely correct.

法线贴图采样
唯一的代码只需要在Surf函数中输入以下代码就行
Normal在使用法线贴图的时候就代表贴图法线
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
voidsurf(Input IN, inout SurfaceOutputStandard o) { // Albedo comes from a texture tinted by color fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color; o.Albedo = c.rgb; // Metallic and smoothness come from slider variables o.Metallic = _Metallic; o.Smoothness = _Glossiness; //法线贴图 float3 normal = UnpackNormal(tex2D(_BumpMap,IN.uv_BumpMap)); normal.xy *= _BumpScale; o.Normal = normal; o.Alpha = c.a; }
最终颜色控制
Properties控制
1
_FinalColor("FinalColor",Color) = (1,1,1,1)
关键 pragma设置

#pragma surface surf Standard fullforwardshadows finalcolor:final
