This planet uses some of the highest resolution textures available at 8000x4000.
It uses numerous layers to achieve it realistic look and it looks just as good in orbit as it does from far away.
Its the small subtle details that make a cinema quality rendering and this model has been tweaked to even the most subtle details that most artist miss.
