I must take a while, but I'm curious how this can avoid that phenomenon.

You may use a planar pattern to hide that. Just scale and translate it
properly, and add a map or use an alternate wave type to control how it
need to fade near the container's edges.

How do you combine these two(The original and the planar pattern)? I can't spend
time to try it right now, but I wish to look your code (even a simple example).

I think the planar (or equivalent) pattern can be used as an additional density
function (that will multiply with the main one). I did use this for some other
clouscapes atempts.

Multiply is a straightforward idea that combine these functions. I have doubts
about it because it seem change the original pattern (unnatural) ....but I
hardly ever try it. You said that you have used it. Is the effect fine?

The planar pattern start at 1 on the X-Z plane and drop to zero 1 unit
above and under it.
There is no distortion involved.

Also, do not forget the spherical and boxed patterns which work
according to the same principles as planar!! I use them regularly for
atmospheric or cloudscape business.

I once could get this, and IIRC, the truncation was mitigated with such a
function. Alas, I lost the code after a USB stick corruption. But the principle
seems OK, provided the parameters are properly tweaked (tricky).

Lesson :
Backup !
NEVER EVER leave your code and ANY important file in only one location.
Backup !
Several partitions on a single drive is still only a single location.
