Well... I would assume its one of Gencheff's since its his screenshot
Anyways, I have some old images lying around with green clouds that I whipped up into a skybox if youd like. Non-Commercial use only since I dont remember how or when I made these LOL
Anyways, if you want the one in your attached screenshot your going to have to contact Gencheff directly... or edit one from his skybox pack (for which the DL is not up anymore... the site redirects
)
Anyways, here is the one I just whipped up (Special thanks to CE's software, ceSky);
Let me know if youd like it
Cheers,
Anayar
