Hello enscape Team,
one of the things I really like about enscape is the ability to create 3d grass only by naming your material "grass".
Although it might seem like a small detail it can sometimes be, depending on the software you use, a major pain to produce it, so thanks for that!
But, I think with a little more love it might develop from a kind of OK looking 3d grass to a really nice 3d grass...
please take a look at this tread:
pibuz describes how you can break the monotony by randomly placing groups of more defined / hr grass leaves ... I think just by adding 2 more grass types similar to the one pibuz used and sliders to control dimensions and density you could make this a very strong feature!
you might also want to take a look at lumion 8 which has some decent functionality in this regard.
