Tile map component not rendering

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.

The first image shows the project when run from the editor. The second shows it when launched externally. The missing tile map was in a tile map component within an actor.

I have reproduced the same issue in 4.8 beta 4.

Hey tgwozdz,

We actually just released the full binary version of 4.8, and ask that you test in the official release as we will be writing bug reports for this engine version.

Still reproducible in the latest version. Attached is the project which demonstrates this for me. However, this project seems to exhibit a second bug. When opening it, the blueprint’s tilemap renderer component loses its linkage to the tilemap. You will have to re-set this to reproduce the original bug (which causes the blueprint version to not render after exporting). Saving the blueprint changes and reopening the project seems to lose this linkage again.

Thank you for the test project. I will begin my testing tomorrow so if you discover anything new within the time I report back to this post, please let me know.

Cheers,
