If Z buffer can't be accessed as a texture, then depth is rendered in additional rendering pass, using shader replacement.

如果Z缓冲不能被以纹理的方式访问，那么深度将在额外的渲染处理中被使用着色器替代技术渲染。

Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials.

当严重糟朽的历史建筑部件必须要求替换时，新部件要求在形状、颜色、纹理，如果可能，包括材料，尽可能和原始部件匹配。

Camera actually builds the depth texture using Shader Replacement feature, so it's entirely possible to do that yourself, in case you need a different G-buffer setup.

照相机实际上使用着色器替换功能来生成深度纹理，因此当你需要一个不同的G - buffer设置时，你完全可以自己生成一个深度纹理。
