See what I don't get it, how come when we play in the real bedroom we do not lagg but all those bricks creates a huge lag. Makes no since to me.
Maybe that's because the larger in scale something is in a game
does not equal a bigger hit on your performace. It's how detailed they are. How many faces and polygons that something consists of, regardless of it's scale. The actual bedroom map uses a moderate amount of geometry, and doesn't actually have too many polygons and faces for it's size. This build however consists of 33,669 bricks. Times that by 6, give or take a ceratin amount, for how many faces there are in it.
This is rather simple stuff. I'm suprised that you don't actually know this.
