I created two pawns, Pawn1 is a free-fly camera (primary camera) and Pawn2 is a pawn that is running around in circles.
For Pawn2, I added a top-down spring arm camera to create a projection via SceneCaptureComponent2D to create a Mini Map. I did not add any additional Camera component into Pawn2 because SceneCaptureComponent2D component seems to have its own camera. (tutorial reference I used)
Overall, it has been successful. Until noticed that while Pawn2 is doing its own independent movement, then when I move Pawn1 away, the map tiles around Pawn 2 unloads. Here are some snippets
Below is me in Pawn1 looking at where Pawn2 is. Mini map is working well as seen in top-right corner.
Hello, it is definitely possible to have multiple cameras working. Looking at the code, the Pawn 2 must be a Player Controller for it to be recognized. There’s actually a minimap example in Cesium Unreal Samples that you can cross reference.
