Unreal Engine插件打包技巧

打开UE工程，点击编辑，选择插件，点击"打包"按钮，选择输出目录
UE4.26版本打包提示需要VS2017问题解决 1）用记事本打开文件【UE4对应版本安装目录\Epic Games\UE_4.26\Engine\Build\BatchFiles\RunUAT.bat】

2）搜索【%UATExecutable% %* %UATCompileArg%】并删除本行

3）在本行添加【%UATExecutable% %* -VS2019=true %UATCompileArg%】

4）保存并关闭文件

5）重启UE4并打包插件
编译比较严格，需要看报错提示补充类的前置申明以及头文件引用

把打包好的插件，拷贝到工程plugins目录下，删除private源码文件夹，修改".Build.cs"文件，添加编译条件bUsePrecompiled
