## BaseColor与ShadowColor ## Ba8eColor与ShadowColor
- 原神里ShadowColor还会接收其他物体的阴影投射，没有自投影;蓝色协议可能也没有自投影。 - 原神里ShadowColor还会接收其他物体的阴影投射，没有自投影;蓝色协议可能也没有自投影。
BaseColor与ShadowColor的过渡需要Step、Feather、Offset等参数，可以直接制作一个HalfLambert的渐变贴图之后使用View传递。因为有多个贴图所以还需要ID贴图指定。但这样需要考虑一个问题： BaseColor与ShadowColor的过渡需要Step、Feather、Offset等参数，可以直接制作一个HalfLambert的渐变贴图之后使用View传递。因为有多个贴图所以还需要ID贴图指定。但这样需要考虑一个问题：
9体上的同一个ID区域的BaseColor与ShadowColor是否都是一样的
- 一个物体上的同一个ID区域的BaseColor与ShadowColor是否都是一样的
- 如果不一样就需要再传递一个ShadowColor.rgb到GBuffer里。 - 如果不一样就需要再传递一个ShadowColor.rgb到GBuffer里。
- 不管如何手绘的补充暗部也是需要加到GBuffer中的 - 不管如何手绘的补充暗部也是需要加到GBuffer中的
这决定传递到View里面的渐变贴图是彩色还是暗色 这决定传递到View里面的渐变贴图是彩色还是暗色
