Although it may not justify to compare the two products head-to-head as AS Cloud Art comes with additional features rather than just pure-enhancement to the cumulus clouds in Soft Clouds, I think it would still be interesting to find out what the two products bring in terms of cumulus clouds improvement only.
From results shown above, the differences are quite obvious. Although it is not fair to compare the two products head-to-head as mentioned in the beginning, the choice is quite clear if one happens to have both products on hand.
Also note again that there will be no benefit of mixing the two products together. Otherwise, worse may result. Of course, it still depends on one’s own preferences after all.
Lastly, both products are frame-rate friendly as they claim.
Nothing is perfect.
If one prefers something cheaper and light weight, Soft Clouds is good.
With the price of ASCA, REX’s Texture Direct is the real contender, which also comes with additional ground enhancements that ASCA doesn’t provide.
However, if you are using AS P3Dv4, ASCA does blend perfectly well with it.
So, no absolute winner here and it all depends on one’s preferences.
