Thanks nano, you said all very well and I agree 100%. Although my first message did mention Vue's feature list, etc. this was primarily to show why I was looking for the feature that I was asking about. Clearly if Vue did not say "volumetric clouds" in their feature list, I should not expect it. But since they do, and I can't figure out how to use them, as was the case, I figured a Vue forum would be the best place to ask. ;) I also apologize if this question has been answered before. My original messages, that were then swallowed by Rendo (because I tend to write long posts, the PHP session times out I guess), actually included a bit of history about my interest in Vue and that might have helped understand my position better. Long story short I have only been seriously interested in Vue since version 5, and particularly Infinite. So I have only been spending much time here in the Vue forums on Rendo since V5's release, and more so with V5I. If I missed an earlier thread about this very subject, that would be why. I did do a search before posting, but Rendo's forum search feature is not the best IMO and it didn't yield any meaningful results in the first few pages. In any case it's good to get a definitive answer about this, even though it's not the one I was looking for. I will continue to hope for better clouds in the Vue 6 engine, hopefully next year, and meanwhile I hope some Python or materials genius comes up with a way to make a decent approximation with the existing systems. :) - Oshyan
