Скачать или смотреть Custom made LOD System

Hello! I was asked to make a LOD(level of detail) system that is capable of deal with astronomical scale objects(planets, moons, asteroid). It will require a bit more of work, but the main bulk of features is there:
1) It display different objects, from particle systems, to procedural meshes, billboards ecc..
2) Each object can have a moltitude level of details and still barely affect performance.
3) Each level of details can be made by different objects and not affecting much the performance.

To really shine this sytem will require another script to deal with very far away objects, and also i still have few issue that will deal later(when i will know few more things about the whole project:P ).

If you have any suggestions, or want to discuss about it just leave a comment!
