Which folder in fs do I put those file such as perfect water and perfect sky etc... Also what do you do with the AFCAD files Goes the same to Utilities.
Usually goes into the world textures,and the main texure folder,and if a scenery should be in the Addon Scenery main folder, but I think you should read , the read me file and follow the instructions that should be inside the zip or exe file ,o maybe wait until an someone with more experience shows here and help you, Because im not familiar with perfect sky..Sorry
