I'm not sure if Real Clouds X will be the official name, but for now that's what I'll call them! For those of you who don't have REX (and maybe some who do) I am developing all new cloud, sky, sun and water textures for FSX. They are still in early stages of development so I have a lot of work left to do.
Also I am looking for some beta testers. So if you are interested please email me at firstname.lastname@example.org and Ill get back with you as soon as I can! For now, here are a few shots.
