Ox00 Surface Shader Syntax
常用的三种输出数据格式：
//Standard output structure of surface shaders is this:
struct SurfaceOutput
{
fixed3 Albedo; // diffuse color
fixed3 Normal; // tangent space normal, if written
fixed3 Emission;
half Specular; // specular power in 0..1 range
fixed Gloss; // specular intensity
fixed Alpha; // alpha for transparencies
};
struct SurfaceOutputStandard
{
fixed3 Albedo; // base (diffuse or specular) color
fixed3 Normal; // tangent space normal, if written
half3 Emission;
half Metallic; // 0=non-metal, 1=metal
half Smoothness; // 0=rough, 1=smooth
half Occlusion; // occlusion (default 1)
fixed Alpha; // alpha for transparencies
};
struct SurfaceOutputStandardSpecular
{
fixed3 Albedo; // diffuse color
fixed3 Specular; // specular color
fixed3 Normal; // tangent space normal, if written
half3 Emission;
half Smoothness; // 0=rough, 1=smooth
half Occlusion; // occlusion (default 1)
fixed Alpha; // alpha for transparencies
};
