Baked Indirect 模式

Baked Indirect mode is a lighting mode shared by all Mixed Lights in a Scene. To set Mixed lighting to Baked Indirect, open the Lighting window (menu: Window > Rendering > Lighting Settings), click the Scene tab, navigate to Mixed Lighting and set the Lighting Mode to Baked Indirect. See documentation on Mixed lighting to learn more about this lighting mode, and see documentation on Light modes to learn more about the other modes available.

For Lights that are set to Baked Indirect mode, Unity only precomputes indirect lighting, and does not carry out shadow pre-computations. Shadows are fully real-time within the Shadow Distance (menu: Edit > Settings , then select the Quality category, and navigate to the Shadows section). In other words, Baked Indirect Lights behave like Realtime Lights with additional indirect lighting, but with no shadows beyond the Shadow Distance. You can use effects like the Post-processing fog effect to obscure the missing shadows past that distance.

适合使用 Baked Indirect 模式的一个很好的例子是，您想要在与走廊相连的房间内构建一个室内射击游戏或冒险游戏。此情况下的观察距离是有限的，因此可见的一切对象通常都应该在__阴影距离__内。此模式对于构建有雾的室外场景也很有用，因为您可以使用雾来隐藏远处缺失的阴影。

Baked Indirect 模式的优缺点

鉴于 Baked Indirect 模式的性能要求，该模式非常适合以中端 PC 和高端移动设备为目标的构建。Baked Indirect 模式最主要的优缺点如下：

优点

• 提供与实时光照相同的视觉效果。
• 为静态和动态游戏对象的所有组合提供实时阴影。
• 提供间接光照。

缺点

• 相对于其他__混合__光照模式具有更高的性能要求，因为它会将投射阴影的静态游戏对象渲染到阴影贴图中。
• 不会渲染超出__阴影距离__的阴影。
