Unreal shareDDC设置

Posted 2022-10-23 cartzhang

怎么设置DDC，简单记录下。

1、添加环境变量

使用一个BAT文件来实现。

setx /M UE-SharedDataCachePath \\\\10.0.20.5\\TestServer\\Project\\ShareDDC
pause

需要注意的是BAT需要管理员权限来运行，否则有可能会失败。

2、在defaultEngine.ini 配置

[DerivedDataBackendGraph]
Shared=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, DeleteUnused=true, UnusedFileAge=10, FoldersToClean=10, MaxFileChecksPerSec=1, ConsiderSlowAt=70, PromptIfMissing=false, Path=\\\\10.0.20.5\\TestFileServer\\UEProject\\ShareDDC, EnvPathOverride=UE-SharedDataCachePath, EditorOverrideSetting=SharedDerivedDataCache)

3、成功运行后的结果

LogDerivedDataCache: Loaded boot cache 0.19s 81MB ../../../../dev_cartzhangTest_7141/DerivedDataCache/Boot.ddc.
LogDerivedDataCache: Display: Loaded Boot cache: ../../../../dev_cartzhangTest_7141/DerivedDataCache/Boot.ddc

简单记录一下。
以上。
