Creating a new map

Create image.png

  1. Download world map (warning very large file) https://drive.google.com/file/d/1W2oMPj1L5zWRyPhh8LfmnY3_kve-FBR2/view?usp=sharing
  2. Crop the file (recommend Gimp), we recommend roughly 2 million pixels for performance reasons. Do not go over 4 million pixels.
