Hi. I’m using UE 4.20.3 I created new blank test project, packaged DefaultTemplate map with default project settings and it shows fine on mobile until TonemapperFilm effect is enabled (by r.Mobile.TonemapperFilm 1 console command or in DefaultEngine.ini file). After that screen goes black and only UI is visible. This happens on old Nexus 5 (Adreno 330) and doesn’t happen on newer Adreno 540. However in UE 4.16 tonemapper woked fine on Nexus. HDR is on btw.
Hi, I’ve been having the same issue.
I even submitted a bug report but didn’t get any feedback.
Have you discovered the cause? Or better yet, found a solution(workaround, at least) by any chance?
If you have, please share with us.
I just disabled it at all and changed my emissive colors a little bit. It’s not a workaround but that’s what I did 
Yeah, but doesn’t that practically mean we can’t use tonemapperfilm?
Did you find a solution? I have same problem, but in VR mode. Half screen just black, when mobile HDR enable.
