Deviating from Earth Norms in FT?

[waldronate]

Try to avoid the +180/-180 boundary on the world; there may be unresolved editing issues there for one pixel of width. There is also a known problem with certain operation (divide and exponent, if I recall) that can generate infinite values and the software doesn't clip those out so they propagate forever unless you select the area and set the value.

If your area of primary interest is across the +180/-180 boundary and that's the part that is causing you problems, you can rotate the fractal part of the world relative to the underlying edit grid using North Pole Position.Longitude on the Secondary editing page on the World Settings property sheet.

The first picture shown below gives a world with a bad split right across the only land mass. The second picture shows the same world with the fractal part rotated 180 degrees so that the land mass is centered on 0 longitude rather than 180 longitude. Note that doing this doesn't move your editing.
