Yes I understand what you mean by "painted".
Especially after seeing so much REX shots all around, it's hard to say that those little freeware cumulus look good.... however, when you compare directly to the default clouds and really start flying with those new ones, you quickly start to notice a nice addition of details, this "painted" impression in fact adds a lot of "volume" impression, and I quite appreciate it. Big cloud formations can now get really impressive, which was totally impossible with the defaut plain white cloud textues.
There's one point I hate with those new texture though: the various cloud "elements" are way too much "round", I will discuss with the author to check if he can produce some more "irregular" shapes in the next version
