模型

顶点颜色：

模型的B通道灰色

贴图资源

SOL_base_基础色块效果：

其中SOL_base_A通道的效果：

• 其中A通道，是将人物身上的文字图案区域 描黑。

SOL_ilm：如下

SOL_ilm模型上区域分布

如下：

- 左到右，依次为RGBA。

• R通道：控制整体的高光强度。

• G通道：控制NdotL光照的偏移值，例如褶皱。

• B通道：控制高光的大小、范围或者形状。

• A通道：人物模型的内描线。

• 顶点颜色：

• R通道：AO，也是控制NdotL光照偏移。

SOL_Sss：如下

SOL_ilm在模型上的效果

SSSTexture的值与环境光的颜色相乘得到的颜色来决定阴影颜色。
明部主光颜色
暗部 环境光颜色
