Thinking about the first look, and glancing at the edge of my current monitor a couple of additional sheets would do it. In this example (originally MS Overland which I know all users have) I have added an INNER BORDER and OUTER FRAME sheet setup and drawn a shape on each to represent those parts. Both are on the SCREEN layer.

The 'monitor off' background is just a grey polygon on the BACKGROUND sheet, which I moved to the MAP BORDER layer and resized to include the border and frame details for an automatic export of the whole. I then froze the MAP BORDER and SCREEN layers as is my habit.

I hope this gives you a few ideas.

I'm not sure what you are after with the second look.

If I were doing this I would first make sure the source maps covered an identical area by trimming them together in an image editor (PS, Affinity Photo, GIMP - take your pick). Then I would turn on the snap grid and import them one after the other, using the same snap points to define their extent. Once they are in CC3 you can scale them together, so keeping the alignment you've already set up.

There are probably many other ways you can do it. This is just the way I would do it.

This might help. The difference between a plateau, a mesa and a butte is one of scale alone, and mesas may be a huge range of sizes.

A plateau may be thousands of square miles in area and is usually flattish on top, while a mesa is an eroded section of a plateau that has cliffs all around it. Mesas are wider than they are tall. A butte is an eroded mesa, much smaller, and usually taller than it is wide.

This week, Ralf will be taking a look at the Character Artist add-on for CC3+ to build a character and a monster, and create a paper standee for printout.

Have you looked at The One Day Worldbuilder pdf included with FT? (ProgramData\Profantasy\FT35\Documentation)

I'm not suggesting that you make a whole world, but it might help you get a few ideas about resolutions and methods.

Remember that if you change the resolution on an existing world the shape of the landmasses may change quite a bit.
