Well, if you just want to use that zoomed-in portion as it is, then all you have to do is to use pick Rectangular section JPG when you save the map, this causes CC3+ to prompt you for two opposite corners that define your export area instead of exporting the entire map, this allows you to export arbitrary (rectangular) portions of it.

The wave fill is defined in each template, so you'll need to edit it for every map you want it changed in, but what you can do is to go to Symbols menu -> Symbol Manager, then check the box that says display fill style symbols. You should now find the Wave fill symbol in the list. Select it, and hit edit. Define the two corners of the editing window as CC3+ asks you to do, and then simply use :CC2MCHANGE: on the waves and make them black. Close the editing Window, and say yes to keep the changes.

For easy ways to place those symbols, either set up a snap grid matching the size of the symbols, or you could probalby get them placed on a line with Symbols Along using the appropriate parameters.

Also note that the change properties dialog defaults to the currently active settings as shown on the status bar, they are NOT showing the properties of the currently selected entity, so nothing is "reverting back" here.

Looks like the display have been corrupted somehow, this is not normal.

Does quitting and restarting the program help (it should automatically reload the last open map)? If so, you have a workaround, but you should probably still contact support.

Check with support. If you already own CC3+, they might provide you a copy of CC3 or find another way to provide you with a solution for getting the symbols.

Not as a finished feature built into the program, but you can do this using a Macro.

The Large Exports annual contain such a macro with explanations (the end result with this macro is to combine the individual tiles into one large image, but the start of the macro exports the map as smaller tiles.)

A very nice map. Looks great. I've always been very partial to SS2 myself.

I am not familiar with PlanetMaker, but it seem to just need a flat texture to import.

What I did as a quick test was to export my map as a 4096 wide jpg. (Using file -> save as and picking the jpg picture file file type)

Then I exported it again to a new file to get the heightmap, this time as a 16-bit greyscale png height file.

Then I switched to the normal map view and exported that as well, using the jpg picture file type.

Unfortunately, the way FT exports these, it keeps the unused area in the window as part of the image, so you need to crop them all in an image editor, make sure to crop them to the same size.

Then, in planet maker, set it up to use the tree textures you exported as surface, bump map and normal map respectively. (you won't have a specular map, so leave that blank, same with background unless you have something you wish to add there)

The reason I did all that is because that doesn't just bring the flat image into PM, but also the height data and surface normals for a better representation. You only strictly need the surface map if you don't have anything else (which would be the result from making it using wonderdraft as the video did), but it can look better with normals and height map, and since FT3 do have the ability to export these, I added them to take as much advantage of the FT3 - PM combo as possible.

As for your seas, I guess you exported that one from the Gaia view in FT3. It is designed to be a simple pretty view, but it isn't configurable at all. Try basing the export on the altitude view or the texture climate instead. I believe that will give you better results.
