After cooking, If user installs same project which contains drawing material via DrawTile function in HUD, is not displayed in es2, with MobileHDR off (verified on android device)
DrawTile script is in MyHUD.cpp it is okay in PC and mobile with MobileHDR on.
Open attached project and try launch on device. (You might need to build project, since binary files are not included)
Game\UI\TestMaterial is not displayed.
