Hi, Anyone actually knows how to define Maps and Sets in Blueprint Scripting? Is it actually possible, or is it C++ only? I really can’t seem to find any documentation on this other than the C++ TMap data structure. Sorry if the question has already been answered, but since maps and sets are words…

You have to go to Editor Preferences>Blueprint Editor>Experimental. Its the second option that says “Enable support for TMaps and TSets.” Don’t jump on it, the feature is unstable and nonfunctional, at all, you can do anything with it.
