前言

我使用unrealEngine5.7.4创建了使用第三人称模版创建了蓝图桌面工程命名MyGameFPS，创建基础关卡，然后再工具菜单Platforms->Cook Content ->Cook Content
ue编辑器右下角提示：Cooking failed!
然后我点击Show Output Log 后，窗口显示错误信息，

请问发生了什么错误，为什么导致错误，如何解决?

我什么都没做尝试第二次烘焙，提示成功了，为什么呢？
主要原因是第一次虽然最后被判定失败，但它其实已经做完了大量工作：
LogCook: Display: Done!
Shaders Compiled: 7,578
NumPackagesSaved=526

第一次失败发生在 shader 编译/XGE/IncrediBuild 相关路径里，但很多 shader 和资源已经被编译并写进了缓存，也就是 DDC / Derived Data Cache。第二次再 Cook 时，日志显示：
TotalGetHits = 4795
TotalGetMisses = 0
GetHitPct = 1.000000
Assets Built = 0

这说明第二次基本都是直接命中缓存，没有再大规模重新编译 shader，所以绕过了第一次容易出错的重编译阶段，21 秒就完成了。

简单说就是：第一次像是“边失败边把作业写进缓存了”，第二次直接用缓存，所以成功了。

但这不代表根因完全消失。你的环境里仍然有 IncrediBuild License not activated 和 XGE shader compile 的隐患。以后清空缓存、换材质、升级引擎、换机器，可能还会复现。稳妥做法还是禁用 XGE shader 编译，或者正确激活/修复 IncrediBuild。

一、彻底解决

1.修改GameFPS.uproject文件
/MyGameFPS/MyGameFPS.uproject
使用notepad++ 打开

{ "FileVersion": 3, "EngineAssociation": "5.7", "Category": "", "Description": "", "Plugins": [ { "Name": "ModelingToolsEditorMode", "Enabled": true, "TargetAllowList": [ "Editor" ] }, { "Name": "GameplayStateTree", "Enabled": true }, { "Name": "XGEController", "Enabled": false } ] }

2. 修改ConsoleVariables.ini文件
   /MyGameFPS/Config/ConsoleVariables.ini

; Keep shader compilation local for this project. ; The XGE/IncrediBuild path can fail when IncrediBuild is installed but not licensed. r.XGEShaderCompile=0 r.XGEController.Enabled=0

二、成功

再次Platforms->Cook Content ->Cook Content
