Attached is a Pov file for the Earth using a specular map.
The image maps are to be found on the Blue Marble site. They are large.

If you can't find any particular map from the names. Let me know and I 
will upload it.

The scene was created in Bishop3D so you might get a few warnings.

Awesome! Thanks.

Do you find any overall speed improvement using Render_Block_Size=8?  Or 
is it just more fun to watch it render? ;)

Interesting it is a 10,000 frame animation, yet the source doesn't use 
"clock" anywhere, so every frame is identical. :)

Yes a bit. Especially with media and lots of reflections.
But the real reason is for that last block that takes hours to render 
and there are cores lying idle. It annoys the bejasus out of me. :)
At least this way I can have 12 threads working on it.

That's how the modellers, I've used, work to create an animation. They 
output one scene file for every frame and use the 
Subset_Start_Frame/End, ini commands to control it.

I generally write the animation code myself. After setting the scene up 
in Bishop3D. I prefer to use frame_number rather than clock. Clock is so 
analogue ;) You know where you are with frames.
