Not out of the box. There are a few possibilities like the WebUI plugin but this is quite project specific. I would say that something like a json library would be quite awesome but BP doesn’t really have dictionaries in the common sense. You’d be left with potentially multidimensional structs which is not quite what I’d call user friendly… Especially since you’d have to dynamically create them. Come to think of it I wouldn’t know a proper way to port a json object (or any way developed to get a lot of data from server to client) directly to BP even if you’d try. You’ll probably have to write a wrapper for your specific values and get them with a simple getter for it from a call in BP… unless you plan on adding dictionaries and multidimensional arrays to the engine.
