From the last thread:
It's CONFIRMED!!!! Snow accumulates!!!
"Accumulates" doesn't necessarily imply volume, however. I think it's clear from the article that it at least means
where snow gets distributed. I feel like the wording in this article is the same information as the magazine article, so we already knew it "accumulates" anyway.
Now, with that said, the article also clearly indicates that it's somehow
precomputed/artist-defined. So even if they somehow achieve volumetric snow (which, again, I doubt) it'll probably be static and leave you unable to interact with it. Meaning no knee-deep trudging or other things that people have assumed from such vague statements as "snow falls where it should" or "accumulates realistically".
If you want to read my anolysis in-depth, you can see my post here: http://www.gamesas.com/index.php?/topic/1158033-amazing-snow-and-enviroments/page__st__20__p__16971345#entry16971345
So, don't confuse "volumetric" with a possibly precomputed effect that the artists have painstakingly defined in advance, if that's even the case. It's also clear from the screenshots in GI that the snow indeed "lands realistically" on surfaces, but is completely flat.
** Which I'm perfectly fine with. I'm also perfectly fine if they fake volumetric particle interactions with some animations near your feet, creating upkicked snow and such, as in Uncharted 2's snow levels.
I'm still betting on a Crysis Warhead-like snow shader, when it comes to the pixel shader that "places" the snow realistically on surfaces. And it seems they have incorporated into their engine a way to let the artist have control over what gets the snow shader and what doesn't. We can't assume any more than that from what we've been given, so "Snow accumulates!!!!" sounds presumptuous and gives people false hope.
Like I've said many times, I'd be delighted to be wrong.
