@MasterQ32: Cool, but remove the ".zip" from the project name please How does the structure of the "level1.owl" file look like?
@Sivan: You seem to have found some nice ways to speed up the level rendering process (LOD, PSSM, ...). It would be great if you write a tutorial about how to design large outdoor levels properly!!! (We could ask George if he offers a "tutorial contest"!)
