This is a photo realistic model of mars as it will look like when the planet has been successfully terraformed and inhabited. 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. It uses a futuristic art style kinda of like the planet Coruscant from the movie star wars.
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.
