Destructavator:
Considering scale, it was mentioned that the carriers are only a few hundred meters in diameter - Considering the size of a typical moon large enough to form into a sphere like that from enough mass and gravity, and have lots of craters, wouldn't the shadows also be only a few hundred meters in diameter and therefore be so small in comparison that a viewer in space would see no shadow at all on the moon?
Think about this - I live close to an airport, and once in a while I see an aircraft pass overhead and for a split second can see a shadow from it zip across the ground. When I see this, the shadow is about the same size as the aircraft. (The sun is very far away by comparison.)
In these video clips the shadow is being amplified to a much larger scale because I'm guessing the virtual light source is much closer. It makes it look like the moon would only be several alien ship lengths across. To be more realistic, I'd think the shadows would be so tiny compared to the size of the moon that they wouldn't be seen at all.
Therefore, to be realistic, the ships shouldn't have any shadow at all on the moon, only on each other (If one ship is in front of another nearby one).
Does this make sense?
At least consider this - If a manmade satellite passes overhead, does it cast a huge shadow the size of France moving across the Earth? (And we have launched zillions of them up there now, from various countries.)

--- Quote ---Second, this would be so awesome as part of an intro cinematic, perhaps tacked on before the start of the script we've already got. So it would run something like this:
1) View of Earth from space, filling up the screen. Camera slowly pans away to focus on the moon, where the carriers come in and do their fly-by. Whole scene is silent, only music playing.
2) Last Carrier disappears off below the camera. Cut to a view of the launch bay sending out a UFO (Scout or Fighter), which the camera follows towards Earth at breakneck speeds. Still totally silent, music only.
3) Cut to a static wing-mounted view of the UFO, looking straight at the cockpit from the wing. Little wisps of atmosphere start to come in, and the UFO heats up slightly. The camera starts to shake more and more violently. A roar of wind slowly fades in as the atmosphere thickens, growing louder and louder, the only sound in the world.
4) The camera stops suddenly at a fixed point above a large city, watching the UFO fly away, tracking it as it flies over the city. Fade out as UFO starts to turn.
5) Cut to original intro script (alien walking towards burning city).

--- Quote ---Thats a week rendering time.
I make more short clips, then it can be composed to an movie by Destructavator.

Actually, much of this really is possible; if sitters can build all the components, I could easily put it all together, complete into a roq (or almost any other format), and on my end it wouldn't take too long to render on my computer, I would probably spend more time setting it up, selecting filters, transitions, panning, etc.
sitters:
OK I have render an new one, with the light source in Cinema called sun.
I only can control this light with time and date.

I going to make now other stuff.

The situation is different because Earth has an atmosphere which refracts light (think of the way light behaves in a fog). The moon doesn't have an atmosphere at all, so sunlight doesn't get refracted and the lighting as a whole is much more direct.
