Normal Pass

普通通行证

This pass (also in combination with the Positions Pass) can be used with any 3D-capable composition program (e.g., The Foundry Nuke or eyeon Fusion) to create all sorts of effects such as re-illumination or re-shading without having to have the actual 3D geometry at hand.

这个通道(也与定位通道结合)可以用于任何3D 能力的组合程序(例如，铸造核武器或目光融合) ，以创造各种效果，如重新照明或重新阴影，而不必有实际的3D 几何在手。

The Normal Pass is an enhancement (with various modifiable parameters) to the Material Normal Multi-Pass function.

“正常通道”是对“材质正常多通道”函数的增强(具有各种可修改的参数)。

A Normal Pass encodes the direction of the visible surface normals as an RGB image.

Normal Pass 将可见表面法线的方向编码为 RGB 图像。

Tip: 提示:
 Because the positions are encoded in 32-bit and can also contain negative values, such a pass can only be saved in 32-bit. The following formats can be used: B3D, OpenEXR, PSD, PSB, TIF. OpenEXR is recommended. 因为位置是以32位编码的，并且还可以包含负值，所以这样的传递只能保存在32位中。以下格式可以使用: B3D，OpenEXR，PSD，PSB，TIF。推荐使用 OpenEXR

Note that Photoshop CS5 often has difficulty with negative values and cannot correctly read the OpenEXR layers.

注意，Photoshop CS5经常有负值的困难，不能正确地读取 OpenEXR 图层。

Make sure the following are enabled in the Render Settings menu when using this post effect:

确保在渲染设置菜单中使用这个后期效果时启用以下功能:

Edge antialiasing is purposely not included in the Position Pass because this would make it unusable.

边缘反走样是故意不包括在位置通过，因为这会使它不可用。
