Title: Earth orbital render on BBC website looks kinda familar

Take a look at this

Stunning renders, although the ship could do with some work. Anyone know what software was used to make the background.

It looks like TG2, but I have no idea.

The background is probably a photograph with a simple object render composited onto it.

Yeah, but I like my answer better.  LOL

I saw an article on the BBC website recently that had a picture that looked like it was made with Terragen 0.9...

I'll see if I can find it again...

TG 0.9 or not?

Yup, I guess that the BBC is too cheap to upgrade to TG2 :P.  Actually, though, they also decided not to shoot the new Doctor Who in HD due to increased rendering costs for VFX :(.  This apparent cost-cutting brings a whole new meaning to Monty Python's "The BBC is Short on Money!" sketch ;).

actually, the original post is a picture from the ISS (the space station) of a sunset. here's a high-rez version of it (3032x1986)

Wow now that is lovely, definitely something to aim for and I'm sure its within the realm of TG2 possibilities.

One thing has been puzzling me is the orange highlight of the suns reflection. the reflection from the sea is orange but the clouds are white apart from their forward facing highlights. The only way I can see of doing that (in TG2) at the moment is to make the light source orange but that will change the colour of everything. Is there anyway to modify the colour of a highlight or reflection independently of the light source?

 :o Amazing.
That photo shows us how good TG2 is already - I've seem very similar images generated by TG2. :D

That's because the clouds are at a higher altitude than the sea. The sunlight that reaches the sea has travelled through more atmosphere and so is more red due to the way the atmosphere scatters light. It is even more pronounced because the light from the sea has to come back through the atmosphere before reaching the camera, so it is reddened even further. The same thing happens to the clouds but because they are higher in the atmosphere the sun needs to be much closer to the horizon to achieve the same degree of reddening.

Not only that, the clouds are lit by both sunlight and other light coming from all directions (mostly from the surrounding sky), whereas the highlight on the sea is a concentrated reflection of only the sunlight.

TG2's atmosphere should be able to simulate this effect without resort to any special tricks. The most difficult part is to create realistic cloud shapes.
