Mobile material error (show only black)

Hello,

Target H/W was always Mobile/Tablet.

I already tested with:

  • Scalable without Mobile HDR
  • Scalable with Mobile HDR
  • High Quality with Mobile HDR (right now)

In attach the screenshot of what is happening on device.

By the way, for testing, I switched to new project in UE 4.16.3 for testing.
With this version of engine, in iPhone 5S with works (iOS 10.3.3), but not in iPad 3 (iOS 9.3.5).

The iPad (or iOS 9.3.5) can be the problem?

Thank you.
