Quote - Sorry eonite, of course I meant "density production " and not "density profile". I see how you can create the details with the function editor, but as I said the details produced with the detail amount slider don't look very good. I keep my fingers crossed for a feature that will allow us to modify exactly the shape of those details with the function editor. For example, by using a billow perlin noise or a voronoi node it would be much easier to achieve the shape of cumulus clouds.

Yes, indeed, that would be great if we could access the FE directly from the cloud editor parameters and customize them by using functions.
Actually I`m using Voronoi for Cumulus clouds a lot (at least for the towering part) and the result is quite convincing, but rendering is significantly slower.

However I must defend Vue`s details a bit. I find them rather convincing. After all the Vue details are a sort of billowy perlin noise, while feathering is ridged perlin noise.

What`s a bit hard to achieve is a sufficient amount of details without the clouds "falling apart", because the details are just added. When I use details from the FE I often multiply them with cloud instances. This allows for more pronounced details while the clouds remain compact.

I personally don`t like the "Sharpness"parameter. In most cases I leave it at zero, because when I watch real clouds they tend to be smooth and soft, but NEVER sharp.
