Hi All
Had a quick play and managed to work get a moon that is recognisable in our part of the world
Your standard moon texture map is correctly oriented for the northern hemisphere, when the moon is at an elevation and heading of 0°. Move the moon away from this and technically you have to adjust the texture map to re-orient it (as planet rotation is not possible yet)

Heading 30, Elevation 8
This might look OK to many of you, but what we see down here in Australia is this:

To do this I used a simple Panorama Tools script to remap the moon texture map to a new orientation.
p w2500 h1250 f2 v360 u0 n"TIFF"
m g1 i0
o f4 y-30 r180 p-8 v360 a0 b0 c0 d0 e0 g0 t0The numbers after w and h in the first line are the width and height of the image (pixels)
The other numbers to adjust are in the last line.
y = negative heading of moon
r = rotation angle
p = negative elevation of moon
Technically the rotation angle should also be adjusted according to the moon's position in the sky, but this is a bit trickier to calculate. This simple version at least displays the correct face of the moon
