How I built an advanced 3D Mini Map system in UE

Description :

At 0:00 the video opens with an introduction. At 1:46 the speaker discusses plugin migration, followed by a controller component at 2:09. The mini map opening and closing is covered at 2:37, while movement inputs are explained at 3:23. View inputs and other functions are presented at 4:05, and an inputs flow issue is addressed at 4:27. A custom pawn is introduced at 5:00, and area settings are discussed at 6:33. Area visibility and reveal are covered at 7:45 and 8:18 respectively. Adding a marker begins at 9:11, with the marker class at 9:44, marker transform at 10:45, and marker ID & text at 11:29. A summary appears at 12:05, followed by a manager actor singleton at 12:30. Navigation inputs and process are shown at 13:50 and 14:16, and the view update at 15:05. Render target is explained at 15:55, and a show‑only list at 16:50. Registering an area is at 17:18, with area visibility again at 18:23. Marker actor details are at 19:03, and an area reveal technique at 19:35. Soft references are discussed at 21:35, followed by a pause issue at 23:44. Marker loading stack is at 24:12, and a 2D markers challenge at 24:51. Custom projection is at 27:01, performance at 28:47, tick pause at 29:10, and tick bitmask at 29:32. Saving a marker and area occur at 30:25 and 30:51. Focus markers, brute‑force focus, and focus update are at 32:32, 33:03, and 34:30. The mini map mesh is at 35:10, modeling workflow at 35:45, aliasing artifacts at 36:15, edge technique at 37:20, and the video concludes with an outro at 38:52. Hey! Finally, that beast of a project is done and available to download and use :) Making the breakdown video has proved to be quite a challenge. I did my best though and tried to explain pretty much everything as best as I could. I hope it makes sense and that you can get something out of it. Thanks for your support :) Cheers!
