OSS, lobbies and server browser with UMG and Blueprint

Development Programming & Scripting Blueprint
5

It would be great to get a quick start guide for this. I put together something based on the video and there is basic functionality when I run it through the editor (it completes session bp functions and doesn’t crash)but when I try run a packaged build it crashes out. An outline of my workflow lies below:

  1. Make sure that I’m using the correct version of steam and that it’s selected as my default platform.

  2. Make sure that AppID and other relevant info is setup.

  3. Created a Blueprint extending GameInstance and named it MyGameInstance.

  4. Created Custom Events for Host,Find,Join and Destroy Sessions and connected the relevant Sessions BPs.

  5. Created a UMG server browser (not as tricky as I thought it would be, Yay UMG :slight_smile: ).

  6. Setup switches and messages for Error handling events in GameInstance BP.

  7. Set project GameInstance as MyGameInstanceBP.

I’ve also included the callstack below:

My Engine is built from the github 4.6 release. Anyone had a similar issue with the pre-built binary ?
