There was an extremely long line on the rivers sheet (extending REALLY far beyond the map). Seems to cause a crash when effects were applied. I forced the map to load without effects, then deleted the line. Seems to work fine now.

Looks very nice. Love how you did the central roads and avenue.

The amount of detail really depends on how dens you want your printouts to be. Generally, a normal map is normally more than dense enough for multiple sheets, like 1x2 or even 2x2, but when planning for 3x5, then yea, you'll probably want to include some more details, although probably not 15 times as much. Be a bit careful though, the more detail, the longer it will take you to make the map (and the higher the chance you will feel burned out during the process)

For symbol size, that depends on the type of map you are making. For dungeon/city maps, the scale should be 1 no matter the size of the map. But for an overland map of this print size, I might be tempted to set the symbol scale to half the default value (The default value varies with map size, but you can see and set it from :CC2PRESETS:)

I would probably make a few very simple test maps and then print them to pdf as JimP describes just to see if you are happy with the scale. You could even start out with one of the existing example maps and just see how it turns out when you tile them like you want.

Maps are now in the atlas. Thanks.

Now in the atlas. Thanks for contributing.

That white line is a guideline that shows where the actual nodes are for smooth entities.

I wasn't suggesting you use the actual ferraris fills, just pointed you to that style to show an example of how it can be laid out.

I guess the fills do work out there though, but I would seriously lower the scales of the fills, they're way to large the way they are now. Also, aligning the fills to follow the road (or something else) will give a more organic look rather than have them all perfectly horizontal. If you look at the ferraris style example I liked to, it also uses rows of threes/bushes on the border of the fields. This both looks good, and is often done in real life too.

CA50 is from volume 5, yes.

The bug should be fixed now. I had a function for getting the root of the file name that naively expected the only period in a file name to be the separator between name and extension.

The full color logo is actually quite nice, it gives the impression that this piece was important to get right, and warranted more attention.
