Apologies for the delayed response, this is on our list of updates to tackle and while it does need some updates, it should allow you to get basic steam functionality up and running.
TheJamsh is correct here:
There is some functionality that is not exposed to Blueprints yet and I don’t have a definitive answer as to when those will come online so I don’t want to give you misleading information. In an effort to learn more about Blueprint Networking and Steam integration myself, I used this page to get a sample project up and running which I discussed before on a Twitch Stream towards the end of the year.
This project is now complete and I’ve recorded the video series to go along with it (it’s now in the hands of our video production team and should be released very soon). It will cover several Blueprint Networking topics which I’ve outlined in this thread as well as hosting/connecting via Steam starting from scratch. On the 1/19 Twitch Stream, I will try to show the finished project as well if the video series hasn’t been released by then.
We on the learning resources team are working with the development teams to identify the hurdles encountered when working with specific parts of the engine. We are just scratching the surface here with Blueprint Networking on our team and expect that as more systems get exposed to Blueprints more documentation/tutorials will come online. Please continue to post any comments/issues you encounter as well as that only gives us more ammunition to push our team harder.
