The reason I hadn't chimed in up until this point was that the question has already been answered, Vue can't do true puffy volumetric clouds, since Java Jones didn't want to use the sphere/metablob idea (as it is not truly a viable solution most of the time anyway) he was looking for other suggestions as to how to do it. The problem comes down to the fact that the type of clouds a lot of us are looking for (big puffy clouds that have volume to them) aren't truly able to be made in Vue at this point (or at least I have yet to see an example of one). I speak from experience trying to manipulate volumetric materials and metablobs trying to get the right clouds and resorting to a mix of alpha planes and metablobs to get something halfway decent (see my most recent gallery image). This has been a feature HEAVILY requested by most Vue users on the e-on forums. It's not a case of looking for an easy solution, it's that given the resources and features/limitations of the program, there isn't a good way to do realistic puffy clouds in Vue. I'm not saying you can't do "volumetric clouds" using spheres and blobs, but honestly, they look nothing like true puffy realistic clouds, no matter what the experience level is, I have yet to see a single render showing this method that is even half way convincing without squinting your eyes. If anybody has some real examples to show of this method actually looking like real clouds then go ahead and show it (preferably next to a photograph of real puffy clouds), but I haven't seen it yet. Nuf said, not trying to start a fight, just got tired of seeing Java Jones get insulted left and right because the effect he's looking for isn't available and he's looking to other programs for a solution.
