Hey there!
Thanks for the question - specifically this was referring to the arguments template ref parameter.
So a concrete example of this, would be as follows:
// Stream.json "templates": [ { "id": "incremental-build", "name": "Incremental Build", "arguments": [ "-Target=Incremental Build", "-Script=Engine/Build/Graph/Examples/BuildEditorAndTools.xml", "-set:EditorCompileArgs=-UBA -UBALinkRemote", "-set:ExtraToolCompileArguments=-UBA -UBALinkRemote", ] } ]
Which as a result would be passed to BuildEditorAndTools.xml:
`
Kind regards,
Julian
