Made using the 3D Ogre engine. Not bad looking results. Needs some additional cloud types and a bit more work on the sub-shading/bump cloud details and more cloud types but other then that it looks good.

Indeed. I hope they continue to improve this software. I have been looking for something like this that is easy for doing HDRI skies.
