Thanks @Lorelei , the map is now in the atlas

There is a tutorial on page 94 of the User Manual.

For the map size, it is simply a case of multiplying the number of hexes with their size. Just keep in mind that hexes are wider when measuring corner to corner than edge to edge, so you need to know what those 24 miles of yours actually represent.

I haven't read the text from the annual issue, but if the instructions feels unclear, don't hesitate to give Ralf a word about it. There are many people reading those things that don't hang around here.

Have you remembered to add the Wall Shadow, Point Light Finalize effect? Lighting doesn't start working until this effect have been added.

This is because these maps were made in CC2, before things like effects. So to have a outline on the text, it is actually two text entities with the exact same text, one with regular filled text, and the other set to only show the outline. This was done to make the text more readable.

However, this means that you will need to do the edit twice, once for each text entity. If you have trouble selecting the right one for edit, try hiding some of the TEXT layers (either everyone marked OUTLINE, or everyone NOT marked as such.

As Wyvern said above, it is better that you start your own topic if you have any follow-up questions that are related to your own work and not the atlas repair project.
