I have made map too big, pls help :(

Is there any way to scale the whole map down? I have spend quite a while working on my map but it came out to be too big because I forgot to add an entity in, for a good proportion. :/

 

What is it you're trying to make with this room?

 

I've made this for you. Remove the red dev textures to open it up like the original. (Note: I had to make the entire thing again because the original had a problem where it wouldn't compile right and I was too lazy to fix that and it was easier to make a new map from the ground up.)

 

Also, using the doorframe model I have in there can be helpful for scaling the thing right.
