built-in shaders in Unity have their LODs set up this way:
VertexLit kind of shaders = 100
Decal, Reflective VertexLit = 150
Diffuse = 200
Diffuse Detail, Reflective Bumped Unlit, Reflective Bumped VertexLit = 250
Bumped, Specular = 300
Bumped Specular = 400
Parallax = 500
Parallax Specular = 600
翻译一下就是
unity内置shader的lod 按照如下方法设置的
顶点光照类型的shader 100
贴花，反射顶点光照 150
漫反射shader 200
细节漫反射 ，无光照法线贴图反射，定点光照法线贴图反射 250
法线，高光 300
基于发现的高光 400
视差 500
视差高光 600
