Oh yes - the furniture looks much more like its been battered around.

Arrow slits would be an interesting change from the norm, but either way.

Have you thought of making the walls pop a bit more by playing with the sheet effects on the WALLS and FLOOR sheets?

Create rivers in the normal way (Tools->Find Rivers) and tick the checkbox called 'Keep River Image Overlay' on the dialog that opens once the rivers have been calculated.

Once they are done, you can show the generated river overlay and edit it. This is not the same thing as the vector rivers already visible on the map.

And the only way to find the limits is by trying them ;)

I recommend running through the One Day Worldbuilder, which is included with FT3. That will allow you to take the FT3 world to a free app called Wilbur and bring it back to FT3 with decent river channels nicely eroded in the land. Otherwise you will probably end up with a mass of rivers so dense that the whole map is blue. This is what happened to me when I tried pushing everything to the absolute limits just now. I would say that is down to the lack of suitable channels.

Yes, but it's easier if you export the map to CC3 and edit them as vectors.

If you are exporting the map direct from FT3 and not using CC3 at all, and the problem is that you ran Rind Rivers with settings that didn't give you what you wanted, you can Clear Rivers, and/or Delete River Overlay and try Find Rivers again with longer rivers at a higher resolution (resolution is controlled by increasing the Editing resolution in the World Settings). It's much faster than hand editing.

To get an editable raster image river overlay you need to check the 'Keep River Overlay' box when you initiate the Find Rivers tool, and then open the overlay window and make it both visible and active.

That's pretty good :)

The only problem I can see is that the furniture now looks too perfect compared to the floor.

Ooooo! Booleans!

:D
