Porting from HTC Vive to Google Cardboard - Materials missing

Hello all.

Having this issue where I have succeeded in porting over 99% of a VR game from a HTC Vive to Google Cardboard but certain materials are not showing up, making it so they are not there. This material is for a character, and now its just a floating tablet.

My question is, is it a problem with my materials or my static mesh of the character. The animation of the viable visor follows the correct pathing but nothing shows for the body.
