在安装Visual Studio时勾选了安装Incredibuild，如果系统中同时安装了FASTBuild等工具（如NEXTBuild），在使用BuildGraph执行编译时会优先使用Incredibuild，起不到加速的效果。 解决办法就是在Visual Studio Installer中卸载掉Incredibuild。

Rather than one large asset, these allow us to write an asset’s bulk data (.ubulk) and exports (uexp) out into separate files. This system improves perf in certain circumstances where file read contiguity is lost due to the large size of assets. This feature avoids this by enabling the reader to skip over an asset’s bulk data when seeking to the next file in a series without having to actually have serialized and seeked past that data (since it’s in separate file).

这里有一个Running from a path with a long directory name的警告，然后跟着一个SSH Key的验证错误。 造成这个错误的原因就是因为警告中的内容，而非SSHKey的问题，因为Win默认的路径长度不能长于260，所以当引擎根目录位于较深的目录中时，可能会导致引擎的路径超过限制，导致后续的失败。

注释已经比较说明作用了。而且它还有兄弟宏：
1 2 3 4 5 6 7
#if PLATFORM_IS_EXTENSION // Creates a string that can be used to include a header with the platform in its name, like "Pre/Fix/PlatformNameSuffix.h" #define COMPILED_PLATFORM_HEADER_WITH_PREFIX(Prefix, Suffix) PREPROCESSOR_TO_STRING(Prefix/PREPROCESSOR_JOIN(PLATFORM_HEADER_NAME, Suffix)) #else // Creates a string that can be used to include a header with the platform in its name, like "Pre/Fix/PlatformName/PlatformNameSuffix.h" #define COMPILED_PLATFORM_HEADER_WITH_PREFIX(Prefix, Suffix) PREPROCESSOR_TO_STRING(Prefix/PLATFORM_HEADER_NAME/PREPROCESSOR_JOIN(PLATFORM_HEADER_NAME, Suffix)) #endif
命名有规律是多么重要的一件事…
