v40.00已知问题

[Flak]

各位《Fortnite》开发者，

在v40.00的预发布测试阶段，得益于测试流程的扩展，我们发现了许多问题，并在发布最终版本前修复了这些问题。但仍有个别问题因为发现得太晚，或者为了优先解决更严重的问题，不得不暂缓处理。

我们的目标是在发布每个新版本时，实现问题清零。但是在达成这个目标的过程中，我们希望开发者能够提前了解即将面临的回归问题。未来，我们将继续在版本发布前，分享重要的已知问题，尽早提供相关信息，确保大家能有充足的时间做好准备。

我们了解其中一些问题可能影响各位的开发工作。因此，我们正在为每个新问题制定相应的流程，确保未来版本不再出现这些问题。

我们会在此帖更新修复状态和时间变化。同时，我们还列出了随v40.00版本一并发布、社区最期待解决的既存问题修复清单。

关于我们如何提升UEFN稳定性和迭代效率的具体措施，请点击此处了解详情。

修复了在性能和内存限制内的项目仍收到“烘焙器内存不足”和“烘焙超时”错误的问题

[MAJOR] UEFN “Cooker Out of Memory” / “Cook Timeout” Errors Persist and Worsen After Patch 38.00

Summary The “Cooker Out of Memory” issue in UEFN has worsened since patch 38.00, now affecting projects that are even smaller than the previous threads on the issue, despite them being within project size and memory limits. Projects that exceed roughly 20–40k actors are now failing to cook with either a “Cooker Out of Memory” or “Cook Timeout” error. The data size of the project has no measurable impact — the issue appears tied purely to actor count and the cook server’s inability to properly m…

Gold and Resource UI not visible when enabled using the HUD Controller Device

Summary I’m currently working on a map where it is crucial to the player experience that they see on the resource UI how much gold and how many acorns they have in their inventory. I placed the HUD Controller Device in the world and enabled the appropriate settings, as well as enabling gold UI in the Island Settings, but when in Live Edit or a private playtest code, these are not visible on the UI.
