Making Maps In Koopatlas

Before Map Creation
This tutorial will show you how to create world maps with Koopatlas, and the process of getting them into your NewerSMBW-based hack.

Before we start:

 * The vast majority of the information here is taken from this tutorial playlist created by Lory. The reason this page exists is not only due to the lack of a tutorial on Horizon, but also because the video tutorials are very noisy, distracting, and take too long to get to the point. Additionally, it is unknown whether or not Lory may decide to remove these tutorials in the future, as they are currently unlisted.
 * You can use this Koopatlas interface guide to learn how to use commonly used features.


 * Koopatlas is a software that is known for crashing every once in a while, so be sure to make frequent saves!

Setup
Download the version of Koopatlas that best fits your device, and extract the contents into a folder you want to put Koopatlas in. Do the same for the Doodads. It is recommended to put the Koopatlas files and the Doodads folder in the same directory.

Once you have downloaded the files, open Koopatlas.

Upon loading Koopatlas, it will tell you that you are missing Newer Wii's world maps and tilesets. It will give you a link to download them. Click on it. You can't immediately download them, so just download the entire Newer folder to extract them separately. Since Koopatlas looks for a folder called "Tilesets", simply remove the pre-existing tileset folder, and rename the new one to "Tilesets".

Map Creation
Create a blank map. You'll be greeted by an empty canvas.

First, select the tileset you want to use. For the purpose of this tutorial, we'll be making a small grassland map. Meaning, for this tutorial, we'll choose a grassland-looking tileset. To select your tileset, make a new tileset layer (the grid icon with a green plus sign).
