That’s pretty much how all game characters are made these days.

I appreciate the observations! They’re worth more than 2 cents :)

Indeed, all the hair is casting shadows on the skin in the final composite. Thanks for watching!

I just feel that you’re missing out on some small details.

Regarding the eyebrows: The hairs grow a lot more vertically the closer you get to the middle. And the closer you get to the end, the surface area thins out a little bit. (Although there are a lot more rogue hairs growing laterally upwards, if that makes sense (unless he trimmed them ofcourse))

Regarding the eyelashes: the length of the top eyelash’ hairs shortens as you go towards the edges. And bottom lashes are generally shorter than top lashes. Also, there are usually just a lot more top lash hairs than bottom ones.

By the way, is your particle system casting shadows already or not?

Anyway, don’t get me wrong, I’m not trying to bring down your work, at all, I’m quite a fan :P . These are just “my two cents”.

Kind regards,
Claus

And yes it’s very possible to control the hair length with weight painting. Paint the weight of the vertex group the way you said and plug it into the length vgroup spot at the bottom of the particle panel.

Please don’t misunderstand my tone here – not passive agressive but genuinely curious (text-only-conversation has gotten me in trouble before lol) – and I certainly do want to achieve more realistic results! Though I just checked in the mirror again and think that I interpreted the hair growth correctly…(also when referencing this: http://www.babble.com/cs/blogs/famecrawler/william-mapother-suri.jpg). What am I doing wrong?

Amazing series and really helpful! I have a question though; Is it possible to influence the hair length with a weight paint? i.e. where the weight is 0 the length is 0% but where the weight is 1 the length of the hair is 100%. Thanks in advance.

On a side note, I think you might be able to achieve an even more realistic result by studying hair growth of human eyebrows and eyelashes a little more.

Kind regards,
Claus

Hope it helps. I’ll keep tweaking it to see if I can’t come up with a solution.

Sounds like a similar issue..which I couldn’t solve and thus abandoned. Would you mind posting an image of the issue to the “User submitted images” section on this page?
