Thanks Autumn! :)

I know about the green water, but the truth is if you look at all those other sewer maps out there, for some reason everyone seems to think it's green. Never mind. I've a range of colours.

Well that's another thing. Most sewers are quite small. There really aren't that many you can just take a casual stroll down. And they tend to be tube shaped because that's the most economic structure to use for a volume of liquid.

It does that because the polygons are limited to the edge of the map and the bevel acts on that accordingly. Use the Edit node tool to move those nodes quite a long way outside the map border. Then the bevel will vanish properly beyond the edge of the map along with it.

Looking good :)

With the rivers it might be easier to take one at a time and reduce the line width. You can do that using the change properties tool on the left toolbar.

Be quite careful to observe just one river at a time and look at where it really flows. They don't usually split like you have in the south there.

Most overland styles have marshes, including the Mike Schley style you started with. However, the MS style is so big you might not have found the drawing tool for the marshes.

Alyssa's maps are hand drawn, though we do have an annual style called Alyssa Faden Overland that was created several years ago in this annual. https://www.profantasy.com/annual/2014/november14.html

I would give them a default scale in import for the reasons Remy explained. If there's no scale they don't get smaller when you zoom out or larger when you zoom in. They just stay the same size, which isn't the size you will see when the map is exported.

Giving them a scale stabilises the situation so the tile actually looks the way it is no matter how zoomed in or out you are, and no matter how large or small you export your map.

The "attached version" Ralf mentions is the "Annual Cthulhu City (metric).FCT" file - which is attached to Ralf's comment.

That is correct. It doesn't matter if it's the wrong value.

Don't worry about asking too many questions, Tako. There are never too many questions.

And that was my main answer.

I'm sorry - I did search for the 'official Game of Thrones map' and various other combinations of those words, but I didn't find anything that was some kind of bone fide official map to get an idea of what you want. Instead I got all kinds of very different variations of the same land masses done in hundreds of different styles. So maybe if you could provide a link to the one you regard as being the definitive map I might have a better idea of what you are looking for.

I suggest a hyperlink to the ideal map because every one of these maps are copyright to the artist and should not be reposted here on the forum without their permission.
