We have pretty much cracked the remaining issues with shadows and I think they are good enough to go into our next release. I believe it is a technical first to have consistent shadows zooming from space down to the ground.
There is still some work to clean-up, you can see some slight cracking if you look really close. We can handle these accuracy improvements as we go forward now.
Shadows take up more processing power so we have given you the option to turn them off completely or run them in low quality.
To see the shadows casting between the moons and rings of saturn you can look at my earlier post on planetary scale shadows
In this video I am following the Sun setting across Valles Marineris on Mars.
