Add the easy_atlas folder to: C:\Users\USERNAME\Documents\maya\2015-x64\scripts

• Use your USERNAME
• Choose your maya version

Run the following code from the script editor:
import easy_atlas
easy_atlas.launch()

Note: Example project uses Maya 2020

To target the development script directly to your Maya installation:

1. Find your "maya.env" file in your prefs folder
   1. PC: C:\Users\USERNAME\My Documents\Maya<version>\
   2. Mac: /Users/USERNAME/Library/Preferences/Autodesk/Maya//
2. Open it in a text editor and add this line,
   1. PC: PYTHONPATH = C:\Users\USERNAME\Documents\maya\projects\EasyAtlasTestMayaProject\scripts
   2. Mac: PYTHONPATH = /Users/USERNAME/Documents/maya/projects/EasyAtlasTestMayaProject\scripts
3. Use your USERNAME and the path specific to this project.

Several options to copy the script into the included maya project

1. Manually. Simply copy what's in /easy_atlas to EasyAtlasTestMayaProject/scripts/easy_atlas
2. On Mac, double click the macRunBuild.command. It will automatically do what's in #1.
3. On PC, double click the pcRunBuild.command. It will automatically do what's in #1.
4. If you have node installed, run node index.js.
5. If you have npm installed, run npm run-script build
6. If you have yarn installed, run yarn build

After the Target and Build steps above, open Maya and "Set Project" to your EasyAtlasTestMayaProject directory. Run the following code from the script editor:

import easy_atlas
easy_atlas.launch()

After each change to the /easy_atlas script files, build again to copy the files into the included maya project. Then close EasyAtlas in Maya. Relaunch EasyAtlas using the commands above.
