UV变换主要是在这句代码,TRANSFORM_TEX是Unity内置函数 o.uv = TRANSFORM_TEX(i.texcoord,_MainTex); 可以理解为等价与下面的代码 o.uv.zw = v.uv.xy*_MainTex_ST.xy+_MainTex_ST.zw;//控制uv 这里是计算兰伯特光照的地方,我们获取到光源对象,在获得光线颜色和光照方向。计算兰伯特的公式是Normal 点乘 Light...

SAMPLER(sampler_MainTex); TRANSFORM_TEX用于对纹理坐标进行偏移和缩放 o.uv.xy = TRANSFORM_TEX(v.texcoord, _MainTex); 一些坐标转换函数 float3 worldPos = TransformObjectToWorld(v.vertex.xyz); half3 worldNormal = TransformObjectToWorldNormal(v.normal); SAMPLE_TEXTURE2D对纹理进行采样,传入参数(纹理,...

half2 fuzzUV = TRANSFORM_TEX(UV, _FuzzMap); half fuzz = SAMPLE_TEXTURE2D(_FuzzMap, sampler_FuzzMap, fuzzUV).r; dfg *= fuzz; 1. 2. 3. 4. 5. 6. 使用图片以后,会发现有那种杂乱无章的绒毛的效果了。 然后加一个颜色用于控制第二层的颜色效果。
