When i download regions and try to use them in the game the screen is all flat green grass? am i putting them in the wrong place or something?

EDIT: found out wat was wrong

When you're in region view, press Ctl+Alt+Shift+R at the same time and it will open up your documents folder. Search for the greyscale jpg you downloaded and it should start rendering your region to give it the shape you wanted. It takes a few minutes to render (depending on how big the region is), but that's really all you need to do. ;)

thx neway :)
