Now the project is entering into very important stage.
It is clear that there is no reason either possibility to work with full environment with detalisation level required for close up parts. So the main question now is how to divide perspective view into few logical parts. How many parts do i need, how fast the detalisation will be lowering in each part after nearest. And more, the main goal is to avoid visibility those parts in final work and how to merge this with several cameras in scene.
So, ... research, research, research. Check it and research again.
Spring is coming, hurry up!
