You seem to have some reasonably good maps in your galleries.

Have a really close look at other maps for sale in the same general category as yours. There are quite a few out there that aren't made by humans these days, but you can usually tell because AI doesn't recognise the difference between roads and rivers (just one of the more obvious examples). Once you've weeded out the AI stuff, look at the prices the human artists are setting for their work, the quality of the goods (size and resolution), and compare it with what you are offering.

The final price per copy is up to you to decide, and you might not gauge it right the first time. Better to be a little higher than too low, so you can drop the price if you don't sell anything. Once you've got it right, though, pricing the rest of your work after the first few will be a lot easier.

That's transparency acne.

Sometimes when the pixels in an overlying texture are the same colour as the pixels in the underlying texture, and there is a glow, edge fade, inner, or bevel of either type on the overlying texture's sheet, the rendering engine gets confused and fails to recognise there's anything there on the overlying sheet. So it's read as a pinhole exactly one pixel in dimension. That's why the holes are all the same size.

I have noticed that this is quite frequent with SS5, where all the fills have lots of little black marks, and are all quite similar greens and yellows.

You can try placing a new sheet with nothing on it between those two sheets which does sometimes work, or if it doesn't, copy the overlying polygons onto that new sheet along with the sheet effects. That can also sometimes work without further effort. If that doesn't work either, try changing the fills of the new copy polygons to Solid, and a colour that isn't in either texture. If you have to go that far you may need to increase the width of the edge fade to make sure it doesn't show through.

Try clicking the Text Specs button next to it |CC2TSPEC|. There's probably a very tiny number in the Height box. Put something sensible like 10 in there and try again.

Make sure you have checked the little box called "Send me the monthly newsletter email with any applicable offers" on your Profile tab, and check that your email address is correct. That way you may be able to get it at some point with an offer.

Black Friday is often also a good time to keep an eye on prices.

Ah yes, that will happen if the whole world has been exported. If you had exported it at a lower resolution the detail would be even less when zoomed in that far.

Here is a small group of islands on my FT world

And here is the same group of islands on the CC3 map I exported yesterday (when I exported the entire world at Fine resolution).

This level of detail is fine for the world map, where an excess of detail on every inch of coast would only serve to make the map incredibly slow in CC3, and would be completely unnecessary for the world map in any case, with most of the detail being wasted on our comparitively weak human eyes.

If you want a detailed map of the islands zoom in to the FT map and export again to create a regional map of that area using the same Fine resolution.

This is the result of exporting just those 3 islands from the FT map while I was zoomed in to them.
