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

能夠經過修改

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

修改成%GAMEDIR%DerivedDataCache，修改完的內容爲

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

 

修改好以後從新打開你的項目緩存路徑將會生成在你的項目文件夾內
