I created a new project with source engine 4.5.0. In this new project, I couldn’t use the macros like loop, isvalid and such, which belongs to the standard library. I checked that the standard library is in the engine folder Engine|Content|EditorBlueprintResources|.
Why can’t my blueprint find it; Is it a bug of the source code engine like it doesn’t set up the reference to this lib correctly?
