I’ve running some tests with UE4 lately and I was trying to deploy the realistic rendering scene on my Nexus 5.
Everything works fine, framerate is good too but there are some textures that are missing, for example the parquet floor texture and the door’s one.
I don’t know why as everything else works nicely.
It may be the material’s shader didn’t compile successfully on the device. Please look at your logcat (you can use “adb logcat -s UE4” to see just the UE4 log messages) and see if you see any warnings about materials failing.
