I finally got it working in 4.19, and feel that maybe the wiki may need to clarify something for stupid people like me who didn’t figure it out right off the bat, but the reason only one blueprint copied over and not the rest was because I hadn’t created all of the blueprints I needed in my own project. For each blueprint you want to copy from the Project editor, you have to drag in the same blueprint from Contents in your own project, in my case, I hadn’t dragged in the BP_Sun_Vector_Updater or BP_Underwater blueprints, resulting in those being left out when copying them. The whole time, all I did was drag in only the two BPs that the wiki told me to dump in. Also, if you are making a C++ project, (correct me if I’m wrong) you may have to have the Visual Studio solution saved once (if you just started a new project) in order for to work as well. That may have been why my first attempt failed. Another really important thing I want to address is what I found out the hard way: If you are working with terrains in your project after importing and implementing the Project contents, do not have BP_Ocean selected when you click the “Terrain” tab, it will make your editor crash! While modifying terrains in the terrain editor, do not toggle the visibility of BP_Ocean, it will also make your editor crash! Aside from that, I am really looking forward to using in my project. As of 4.18, UpdateSunPosition with Unreal’s default procedural sky doesn’t work (no matter what, the sun stays on the horizon), and seeing that actually works and looks way better than Unreal’s sky makes me look forward to seeing what I can do with it for my worlds. Thanks for sharing project and keep up the good work!
