I gave in to temptation and warped a copy of the inner crater to the new grid. Looks like I also still have craters on the brain.

Oh well, I might as well carry on...

We have craters now :)

I offered to do that once when it was only about 100 videos, but it would have taken a month back then.

Pick Grid Settings... from the Map menu.

In the dialog, set the Latitude Polar Endcaps to zero.

Click Add, and make sure you check Enable Grid in the dialog that appears (see below).

For the sub-tropic lines set the Latitude Spacing at 35 degrees and the Top and Bottom settings to 35 and -35 respectively. This tells FT to draw a grid line every 35 degrees, starting and stopping at 35 degrees north and south, so you only get one line at 35 degrees north, and one line at 35 degrees south. You will also get one one the equator but you wanted that anyway.

To make sure you don't get any longitudinal (north south) grid lines, set the Longitude Spacing to zero.

You can also chose the colour of the grid lines and the width of them.

Ok both dialogs and you get this

Do the same for the tropics gridlines by adding a second grid and substituting 23.5 wherever you put 35 in the first grid. That should give you something like this. Here I have given the tropics lines a thicker red line. You will see that this second grid appears underneath the first one, but you can move it up to first position using the buttons under the table in that first dialog.

You can hide, show, edit or delete either grid.

I just remembered I hadn't shown the new mesas and buttes. Also 2 new fills - volcanic and wasteland. I think you've seen the red desert before.

The two small mountains top right in this shot are the varicolour versions, matched with the wasteland fill.
