Hi guys
I want to ask some about Map scale, so, I want to make my own 1:1 scale Map and
I think I have to match scale of editor background, map, game background to 1:1:1

I know how to change them. So How Can I make this 1:1:1. Does the game automatically
set the scale?

Sorry about my weird English grammar.

OK. I found how to do that.

but I can't see the whole map in one screen. The background image is so big.
Can't I unzoom more?
