Mobile material error (show only black)
I'm trying to apply PBR for simple objects. In OS X and Windows, works without problem, but in mobile (iOS or Android), the object stays black, without any metallic "feel" or reflection.
I was able to make the metallic look 'n feel using scalar parameters in material, but I wish to use PBR, with images as Metallic and Roughness.
I have made a simple project to demonstrate the error, that is shown in UE4 mobile preview as well.
The screenshots from desktop and mobile attached are from the project. The sample project is also attached as MyProject3.zip (UE4 4.17.1) The images for textures is also in the zip file metal-textures.zip
Can someone help with this? I already read and changed a lot of parameters (even Target Hardware Settings) and I can't make the mobile preview (in UE4) or even iPhone 6S device show the material reflection/metallic properly.
Thanks in advance!

Which difference between desktop and mobile screenshots? Reflection cubemap.
It looks like in your case, on desktop reflections provided by post process screenspace reflections feature. But on mobile post process effects works only on hi-end mobile devices.
So, try to use simple reflection capture actors in your scene - reflection spheres and cubes.
