Issue: Field Papers in June 2017 will not accept Mapbox Studio tiles. This proxy works around the issue, allowing you to compose a semi-dynamic map using it.
For guidance visit: https://fieldpapers-mapboxstudio-proxy.herokuapp.com/
Convert your Mapbox Studio address:
If your style address is: mapbox://styles/mapbox/outdoors-v10
It should look like this:
https://fieldpapers-mapboxstudio-proxy.herokuapp.com/v10/mapbox.outdoors-v10/{Z}/{X}/{Y}.png?access_token=PUT.REAL.TOKEN.HERE
It must not have @2x in the address. It must have .png or .jpg in the address. It must have an access_token.
Then go to the Field Papers custom creator and put the address you just made in as an atlas provider:
http://fieldpapers.org/make-canned-atlas-template
It should appear in the atlas list as "User provided"
