I’m making a paper 2d game using tilemaps. The tickbox to hide layer during gameplay sometimes fails in a launch of the game.
Hello FindersCreepers,
I was able to test and confirm this issue you are reporting on my end. I have gone ahead and entered a bug report for this issue (UE-22623). When a fix is implemented, we will add it to the release notes of an upcoming hotfix or full engine release. I cannot provide a time frame when the fix will occur as it has not be addressed by the developers, yet. Use the bug number I have provided if you would like to search our Documentation or Forums to see if the fix made it into the next hotfix or release.
If you have further questions, please let me know.
Cheers,
Thanks Andrew 
Hey, this still doesnt work for me. Is there a way to fix that?
Thx for any help
The bug is still under investigation and has not been fixed as of late. One thing you could try is to know which layers you know you will be hiding in the tilemap, and make it its own actor, and hide the actor as a separate entity.
Thx for that fast answer.
I will try it
Should be fixed by this PR: https://github.com/EpicGames/UnrealEngine/pull/5354
