Hi @Frozenfire That keyword has been deprecated. You have to use -set:EmbedSrcSrvInfo=true or false now.
Creating dedicated server supported rocket no longer seems possible with these changes in this thread. I’ve tried to build, but server/client targets are no longer included despite the modified InstalledEngineBuild.xml. There is a new xml file called BuildEditorAndTools.xml in \Engine\Build\Graph\Examples folder that supports UE4Server and UE4Client.
