Thanks guys :)

Remember I'm just one of the crowd though. There are lots of others here working quite hard.

You're probably right. It sounds like a form of transparency acne. Try switching out one of the fills (presumably the grey ones) for a slightly different shade of grey and see if that helps.

Thanks :)

You can if you want, Hadrian, but it's easier to put a whole rectangle of sea over the map and cut holes in it making use of the Color Key effect on the WATER sheet.

It's not really an original idea. Most city map styles have the water over the land. It's just an adaptation of that for overland maps.

CC3 requires that you click to place nodes, or to start and end a Freehand Sketch line. It's not an app where you can just draw things with a constant line without any clicking, so the motion of the pen in CC3 is more tapping than drawing. This isn't the way other apps work with a tablet, so it can take a lot of getting used to if you've used tablets in other apps before now.

It might be a good idea to see if you can borrow a tablet from a friend just to see if you feel comfortable with the way it works in CC3 before you make any purchase.

As for user manuals, most tablets come with their own software including a startup and settings assistant. Even my little Wacom has such things despite being the second smallest and cheapest one on the market.
