It's for SGM 2.2 for the people who were looking for it. I am not the author of this addon for SGM 2.2. I would advise you to start up SGM 2.2 and make any changes in the Atmosfear 3 addon before you install GOTZ 2.2 because after you install GOTZ 2.2, Atmosfear 3 will not work any longer! You have been warned.
