I created a simple tile map in the Unreal Editor. I placed an instance of this tile map into an empty scene. I then created an Actor blueprint, with a tile map component within it, with the same tile map assigned to the component.
I set up a camera to show both of these tile maps on the screen. When I play the game in the editor, everything works fine, both are visible. But if I package for Mac, or hit the Launch button, only the raw tile map is visible. The one within the blueprint component isn’t rendering.
Is this a bug? Or am I doing something wrong? I have been able to reproduce this with a new empty project containing nothing but the above two actors and a camera.
