Hello,

I want to make a globe. I ve created a sphere and a PNG-file of a world-map.
But if i do:

pigment { image_map { png "globe.png" } }

it doesn't work. I get 8 world maps on one sphere. Nor Making the worldmap
bigger, neither making the sphere smaller does work. Does anyone have
another solution???

Thank you very much...

Try: pigment { image_map { png "globe.png" map_type 1 } }

Plus reading the documentation, because this is really explained in there!

I've read the documentation, but which map projection do they use? I've
tried lots op projections such as mercator, cylindrical, azimutal,
homalosine projection of Goode, etc.. But non of them give a good result. Do
you know?

I don't think map projections will work. You need an image, where the 
surface of the earth is stretched out to a rectangle, like the image on 
this page: http://livingearth.com/
