这三个反射层设置为添加模式，通过软件遮罩方式的处理，按照我希望出现的地方出现镜面反射或者是模糊反射，侧重于几何物体的边缘和老化模型的处理。
The three reflection layers were set to add transfer mode, using masks I could tell the software I wanted sharp or glossy reflections, focusing on geometry edges to age the models.
许多应用更严重的一个缺点是使用反射会模糊程序内部实际要发生的事情。
A more serious drawback for many applications is that using reflection can obscure what's actually going on inside your code.
这样保证从不同地方反射回来的光更容易区分开，因为他们不会变模糊一片。
This ensures that reflections from different places are easier to tell apart, because they do not blur into one another.
