iOS Packaging shader - undeclared identifier SceneTextureLookup and cannot initialize FMaterialPixeParameters

Hi

I’m trying to package my project for iOS but when the shaders are compiled I’m getting many errors either saying

use of undeclared identifier 'SceneTextureLookup'; did you mean 'MobileSceneTextureLookup'?

or

cannot initialize a parameter of type 'FMaterialPixelParameters' with an lvalue of type '...'

The project has been built for Android successfully so I don’t see why there would be these issues for iOS.

Is there a setting which I can change that I might have missed which could possibly help?

Thanks.

Did this ever get resolved, and if so, how? I am running into the same issue.

Thanks!
