修改UE4的deriveddatacache目錄位置，擴大C盤空間

按照默認安裝目錄，UE4會裝在C盤

C:\Program Files\Epic Games\UE_4.15

DerivedDataCache緩存目錄在

C:\Users\你的用戶名\AppData\Local\UnrealEngine\Common\DerivedDataCache

可以通過修改

C:\Program Files\Epic Games\UE_4.15\Engine\Config\BaseEngine.ini

中的[InstalledDerivedDataBackendGraph]條目下的

Local=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true, UnusedFileAge=34, FoldersToClean=-1, Path="%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache")

中的%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache

修改為%GAMEDIR%DerivedDataCache，修改完的內容為

Local=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true, UnusedFileAge=34, FoldersToClean=-1, Path="%GAMEDIR%DerivedDataCache")

 

修改好之后重新打開你的項目緩存路徑將會生成在你的項目文件夾內
