This is a photo realistic planet of earth if it froze completely over. This model is intended for those who need nothing less then the highest photorealism for cinema quality renders.
The city lights appear on the dark side no matter where you place the sunlight.
This planet uses some of the highest resolution textures available at 8000x8000.
It uses numerous layers to achieve it realistic look and it looks just as good in orbit as it does from far away.
The materials are far from standard and have been tweaked to even the most subtle details that most artist miss.
