Launching UI from BPTryMultiUse

I swear I saw something here a few weeks ago about it, but I can’t find it anymore. I’m looking to just launch a simple UI from a radial menu on a custom structure. It works in the dev kit, but crashes in game. Anybody know where to find a guide on this is, or simply what special way you have to do this for a structure?

Thanks, but everything I download is 0kb. How can I actually download them?

Fixed. Sorry about that.
