I know, that this is kind of stupid question probably. But I am interested in modeling part -> where you have done the door with NGONs. I never know what is correct, all I hear is that mesh has to be topologically correct (and I understand reasons, e.g. for sculpting), but is it okay to create static objects like walls with NGONs and triangulate later, when I would like to use it in game? Is it correct approach, or you wouldn't recommend it at all?
