When setting to iOS or android preview metahuman materials are broken and lids are broken

I believe I am experiencing the same issue, when trying to deploy to android vr headset parts of the models are missing, in one case just the face skin, in another whole head and torso etc… I haven’t yet been able to pinpoint anything though… it works fine if I preview it for PC.

Is there a solution? I’m having the same problem.

Hello, anyone?
