East Europe is a pretty large area. Which part of it? I can then go and have a google street view at what you mean to compare with what I know about existing styles.

A sky island...

When you turn the sheet effects on you could try dding a Drop shadow sheet effect to the LAND sheet, to make it look more like it is flying.

A Color Key only works on the one sheet that it's on. If you want to cut things on other sheets you need to make a new Color Key on that other sheet and add new colour cut out polygons to that sheet above the polygons you are cutting.

I actually missed a point above. The cut out shape must be on top of all the other shapes on that one sheet.

The Colour key works as long as you have these three things set up correctly:

• The cut out shape is on the same sheet as the thing you want to cut.
• There is a Color key sheet effect on that sheet, and its set to the same colour as the cut out polygon
• The sheet effects are turned on.

If you want to cut the same hole in other sheets, for example you've cut a hole in your land that you want to cut in the terrain that lies on it, then you will have to set up the same thing for that sheet as well. It doesn't work for multiple sheets, but only the one its on.

Just to clear up any confusion, here is the spreadsheet showing what is in each pack.
