Looks like Canada ;D
lol, it does kinda.. Wheres africa in that pic?
Other than that, its very cool idea!
looks awesome... good work! :)
i guess thats the sahara desert desert at the bottom, but from the angle/rotation its hard to tell what were looking at
Yes , nice idea, Erwan :)
Not sure but it could be a little bit bigger and the edges a little softer maybe.

Great work on this. It is Africa, though I am having difficulty finding north. (It's the end of my work week; I'm a bit frazzled.) The coastline is recognizable. I like the color shading very much. Softer shadows would look much better.

yeah, Canada, you'll be in for a bit of a suprise when touch down in what you thought was Canada :D ;D
Lake Victoria is near the center of the image, partially in the eclipse path.
I'm rendering a new image to make everyone understand.

Hoping everyone will understand this one...if not, you have the red sea at the top
*note for later: terragen people don't know their geography ;D*

Yeah! We need georeferencing ;D
Nice update! I would make the shadow softer.
I'm on the ISS! :D
this looks better, i like.
The only thing that comes to mind with your image, is that you shadow terminator is far to hard in your image and needs to be feathered and softened but that is the only thing that comes to mind at the moment, that issue aside I like you image.
Regards to you.

That looks great man! Congrats! It is Africa and I can almost see Angola at the bottom from the first image posted.
I was born there, so I know it does look like the African continent. Good job mate.
Just one smal observation though, does the lunar eclipse seem so small? I always thought it would cast a bigger darkened
shadow on the earth? The moon is actually about the size of North America so the shadow would be much bigger.
I know, I am not quite so sure yet, I have to search into NASA website files to check it out myself.
Good job tho! Very nice idea. I like it!
The moon is quite far away, so the shadow area is smaller than you would think. The softer shadow cast area is a bit larger I would think. But I have never seen a photo taken from space to confirm this.

Apparently softer edge is good.

I would set the size and distance of the moon as realistically as you can. Then the default sunlight's soft shadow diameter (0.5) should give you a pretty good approximation of the umbra and penumbra.
The umbra (solid centre of the shadow) is pretty small, because the Moon appears only very slightly larger than the Sun when viewed from the Earth. But there is a much larger penumbra. Because this umbra is so small, small changes to the soft shadow diameter in Terragen will have big changes on the umbra, so you'd probably want to tweak the numbers carefully to make it realistic. (Or find out a more accurate figure for the sun's angle than 0.5.)
At first I wanted to have a real eclipse, but Terragen seems to have problems with placing the moon at the correct distance (3.844e+008 m-->too far?). So I made the moon 10 times closer than it really is, and 10 times smaller.
I just tried again with a very simple scene:
sun: heading 300, elevation 25
moon: distance 3.844e+008, diameter 1.737e+006 , heading 300, elevation 25
camera: near (0,0,0)
When I render with those values, it is still daylight, no eclipse!
But if I have moon: distance 3.844e+007, diameter 1.737e+005, no problem! So I think 3.844e+008 is a too big number for Terragen.

Transfer the distance(or a little bigger) to the radius of the 'background' sphere node. '-3.844e+008'. The Moon is hiding behind it. ;)
