在 UE5 编辑器中，由于游戏设置 -＞ EV100 设置，点击播放前后的光照不同。如何保持点击播放前后的光照一致？
In Unreal Engine 5 (UE5), discrepancies in lighting between the editor and play modes are often due to auto exposure settings, particularly when using the EV100 system. To maintain consistent lighting across both modes, follow these steps:YouTube+1Epic Developer Community Forums+1
在虚幻引擎 5（UE5）中，编辑器和播放模式之间的光照差异通常是由于自动曝光设置，特别是在使用 EV100 系统时。要确保两种模式下的光照一致，请按照以下步骤操作：YouTube+1Epic 开发者社区论坛+1
1. Enable Extended Luminance Range
1. 启用扩展亮度范围
Ensure that the "Extend default luminance range in Auto Exposure settings" option is enabled:Epic Developer Community Forums+380 Level+3Epic Games Developer+3

调整后期处理体积以控制曝光设置：Epic 开发者社区论坛+5Epic Games 开发者+5Epic Games 开发者+5
-
Place a Post Process Volume in your scene.
在场景中放置一个后期处理体积。 -
In the volume's details, under the Exposure section:
-
Set Metering Mode to Auto Exposure Histogram.
将测光模式设置为自动曝光直方图。 -
Enable Min EV100 and Max EV100.
-
To disable auto exposure and maintain consistent lighting, set both Min EV100 and Max EV100 to the same value, such as 10. 80 Level+5Reddit+5Epic Developer Community Forums+5
要禁用自动曝光并保持一致的光照，请将 Min EV100 和 Max EV100 设置为相同的值，例如 10.80 Level+5Reddit+5Epic Developer Community Forums+5
-
This configuration prevents the camera from adjusting exposure dynamically, ensuring uniform lighting.
此配置可防止相机动态调整曝光，确保光照均匀。
3. Ensure the Post Process Volume Affects the Entire Scene
3. 确保后处理体积影响整个场景
To make sure the Post Process Volume settings apply throughout your scene:
要确保后处理体积设置应用于整个场景：
-
In the Post Process Volume's details, check the Infinite Extent (Unbound) option.Epic Developer Community Forums+6Epic Developer Community Forums+6Epic Games Developer+6
在 Post Process Volume 的详细信息中，勾选 Infinite Extent (Unbound)选项。Epic Developer Community Forums+6Epic Developer Community Forums+6Epic Games Developer+6
This ensures that the volume's settings are applied globally, affecting both the editor and play modes. Epic Developer Community Forums
