根因分析

遮挡剔除数据超出分配的内存预算，导致烘焙失败或运行时性能下降。

English

Occlusion culling data exceeds the allocated memory budget, causing baking failure or runtime performance degradation.

解决方案

  1. Reduce occluder count by merging small objects or using LOD groups. For example, in a forest scene, combine 1000 individual trees into 10 LOD groups.
  2. Increase memory budget in Project Settings > Player > Other Settings > Occlusion Culling > Memory Budget (e.g., from 128 MB to 256 MB) while also optimizing geometry.
  3. Use occlusion areas to limit culling regions, reducing overall data. Place an OcclusionArea component over high-density zones only.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Simply increasing budget without reducing data can lead to memory spikes and crashes on low-end devices.

  2. 60% 失败

    Disabling culling removes performance optimization, causing draw calls to spike in large scenes.

  3. 70% 失败

    The error is not version-specific; upgrading alone does not reduce data size.
