修改DDC缓存位置

会把项目缓存，存在当前项目下；例如把这个项目发给别人的时候就不用人家重新-编译着色器

搜索这个

InstalledDerivedDataBackendGraph

或者直接搜这个也行

%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache

改为

%GAMEDIR%DerivedDataCache

或者使用下方bat 执行路径替换内容

Modify_DDC_loc_EN.bat

@echo off

chcp 65001

echo ===================================================================
echo =								  =
echo = Replace the DDC local cache path to the project root directory  = 
echo =								  =
echo ===================================================================

setlocal enabledelayedexpansion

REM Prompts the user for a path

echo This script will put "ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache"
echo replace "GAMEDIR%DerivedDataCache"
echo Please enter the path where the BaseEngine.ini engine is located below:
echo Hint: ".. \UE 5.4\Engine\Config"
echo ===================================================================

REM Gets the path to the input

set /p userPath=

REM Replace the path entered by the user into the 'path_to_file' variable

set "path_to_file=%userPath%\BaseEngine.ini"
set "search_string=%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache"
set "replace_string=%GAMEDIR%DerivedDataCache"

REM Read the contents of the file line by line and replace the specified string before writing back to the original file

for /f "delims=" %%a in ('type "%path_to_file%" ^& break ^> "%path_to_file%"') do (
    set "line=%%a"
    >>"%path_to_file%" echo(!line:%search_string%=%replace_string%!
)

REM Prompt to exit after 5 seconds
echo Done  Exit in 5 seconds
ping -n 5 127.0.0.1 > nul
exit

Modify_DDC_loc_ZH.bat

@echo off
chcp 65001

echo ==========================================
echo =    替换DDC本地缓存路径至项目根目录下   = 
echo ==========================================   

setlocal enabledelayedexpansion

REM 提示用户输入路径

echo 将会找到 "ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache"
echo 替换为 "GAMEDIR%DerivedDataCache"
echo 请在下方输入引擎BaseEngine.ini所在的路径:
echo 提示："..\UE_5.4\Engine\Config"
echo ==========================================   

REM 获取输入的路径
set /p userPath=

REM 将用户输入的路径替换到 path_to_file 变量中
set "path_to_file=%userPath%\BaseEngine.ini"

set "search_string=%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache"
set "replace_string=%GAMEDIR%DerivedDataCache"

REM 逐行读取文件内容并替换指定字符串后写回到原文件中
for /f "delims=" %%a in ('type "%path_to_file%" ^& break ^> "%path_to_file%"') do (
    set "line=%%a"
    >>"%path_to_file%" echo(!line:%search_string%=%replace_string%!
)

REM 提示完成
echo "完成,五秒后退出."
ping -n 5 127.0.0.1 > nul
exit
