I having this issue that im not seeing other people have
so when i try to use custom pbr materials in my games they only show up in studio, but not the actual game
In studio:
In game:
not 100% sure whats going on here because i see other games that have working custom materials 
Out on a limb here but maybe your in game settings has graphics quality on lower than your studio settings… go to settings in the game and change it to highest level and see if that helps.
I think its because the feature is in beta
Custom materials are still in beta so they won’t show up in games yet.
They may just be using meshes with PBR textures.
it just started working randomly, no more replies please
