%obj.setScale("0.940827 1.97505 1");
I copied those numbers from kitchen.mis
I did some testing w/the spawnsphere. It seems it would be better to think of it more like a spawn column, where the column is always 100 units tall, and the player is always spawned at the top and then moved down until it hits something.
So... I think you could move the spawnsphere down ~90-95 units, and it would start spawning the players inside of the map.
