UE4.7.1 needs to compile shaders for the instanced meshes(Foliage) every time I start the editor,and the material changes to default when I package for IOS.Thanks!
Hey -
Thank you for your report we are digging into the issue now, can you let me know what your foliage material setup is, a screenshot would be most helpful. If you are referring to the new Two Sided Foliage Shader Model, this shader model is another form of Sub-Surface shading just more performance friendly however this shader model is not currently supported on Mobile Devices.
Thank You Again -

Hey -
The Material you are picturing above seems like it would be okay on a mobile platform, but just to confirm can you take a screenshot of the Material Attributes details panel as well.
Thank You

Oh I have found that after I upgraded to 4.7.2,the issue did not happen again.Thank you.
