So i made a map, which is my first map, And i need help with the thumbnail. When i tried to put a thumbnail in this happened...
on your "info.json" file , you have to write the name of your thumbnail file (previews:....) : also , be aware to resize your thumbnail file to the standard 400x192 format
Stupid question but what happens if it isn't that size? I am using one now that is 1895x1008 (CTRL+P screen). Seems to work fine. Is 400x192 the 'favored' format size and not a requirement?
