This small tool for Unity inspired by Nvidia GPU Gems which i personaly recommend.

Repo Map:

main____ // You are here

    |
    
    stable // The feature-cutted, but stable (probably) version.
    
    |
    
    scratch // Trashcan for all untested ideas or half-working solutions

How to:

1. Download the Archive from stable and move the folder Impostors to the root of your Assets folder.
2. Remove all the objects from the background which do not have to be baked.
3. Open the Tools -> Impostors Baker (Name in context menu may differ) and Bake.

NOTE: This Repo is really raw yet, i would upload features "by bits" while some of features are not tested yet so not sure they worth to be.
