It is good if we use material Id system instead material masking…???..It is good or not
It depends.
What do you want to achieve?
what…???
Ok, then you free to do everything you want. Unreal is powerful engine and it can handle many things.
About your question - using many material ids on one mesh will affect performance, so for games we use masks. If you don’t care about polycount and number of material ids - use it as you wish.
Anyway, there should be some limitations.
Look Bro…i am not game developer,i am Architecture Student so that mean i don’t care about game play or how many fps my player will get…I JUST WANT QUALITY…!!!
like…what…???
