Really love sansar but i've just recently started to work on some hair and what hit me, is that while polycount of 8k seems like a lot for hair at first glance, it really falls short when trying to make more complexed hair styles. In this post i'm going to post some examples of hair which would highly benefit from increasing polycount of hair to 15k. (or at least 13, please!)
As you can clearly see, i'm talking primarily of complexed hair which blends between braided hair and hair cards. with current polycount limit, it i will be impossible to create that kind of hairstyle while retaining high quality.
Also, another issue i'm finding is that creating flyaway hair which add to the silhouette of hair is also extremaly difficult to do at the current moment as we're limited by the polycount.
