You mean the mask? You have to set what each one will be. See where you can select the different terrain type? Change between 1,2,3 and enter different terrains in!
Thanks, I do that, but it remains the same; the mask doesn't match where I've placed it, I mean;
I use red for mask 1/ the main map terrain.
Green for such things as water for the "holes" I've created in the map and blue for the use on mountains.
I've followed a tutorial on youtube and it worked perfectly for a previous map I created. But for some reason, not this one :/
It just remains all the same colour, rather than being "broken up" into different parts of the mask and having different parts being different terrains.
