Have a weird material / lighting issue I’ve never run into before (granted, been only using UE4 for a few days now). As you can see, 
it looks fine in Max 2013. But when I imported and applied the material in UE4. . . i get that. This screenshot was taken after blowing out all the lighting too.
I’ve unwrapped it twice now, thinking it was a lightmapping problem but nothing.
I’;ve gone over the material again a few times as well but I can’t find anything wrong either (set the base tint alpha to 100 in the master material too).
I’ve tried different light build settings too.
Any ideas?
