I did turn up turn up the Quality Boost and Scattering Anisotropy as well. To be honest it's all how the code was written and there is nothing that can make those clouds look any more real then what Vue can do already. The atmosphere and volumetric cloud code just has to be re-written if better results are needed so it looks like this is what we get for now. I would show off my results but they are not worth it as we all should already know Vue's limits by now. All i have to say is a voxel-based particle system is the way to go but i fear the render times will be insane knowing that i can not even use displacement in Vue without killing the program. Ah well, can't say i never tried.       :)
