Hair in Blender

Postby Carlossedd » Thu Jan 05, 2017 3:41 am

Hey guys, so i've watched a couple tutorials on making hair, but am still having some minor difficulties and I was hoping someone could chime in.
The hair looks fine from far away, i'm just having two small problems, first the hair seems unusually large, it almost looks like rope when I zoom in. And secondly, at the split idk what the hell is going on, it's a bunch of short hairs and I haven't cut it. I dont care too much about the thick hair, though if I could make it more real like that would be nice. The thing that bothers me is that split, it looks weird and creepy.
Optimally, I'd like to make my hair look this thick, and the split like this (http://www.makehumancommunity.org/cloth ... ft_01.html), but if that's not possible, i'd at least like to fix that damn split.

I believe all the relevant settings are displayed, but if there are any that aren't ill get them for you.

Thanks in advance!

The cycles Hair rendering and settings at the very bottom on the particles panel are critical that is where the thickness of the individual hairs is defined so lets have a looks at those first ;)

Enjoy the Choice :)

I don't think these are the problem, but here they are.

Shape = Thick ? try Thin
and for Root .02 not .2 for the tip -.8 which will thin the stands and the Tip value will give you pointed strand tips

Hmm, the root at .02 looks a lot better, but it made the split WAYY worse, now she's more bald :(
The settings for tip dont go below 0 and there is no "thin" shape, only tick and "ribbons"

The hair is done with three different particle systems.

This way you can control the split much better. It's also easier to comb.

Somebody else is struggling with this problem, but don't give up. It really is possible ;) In my tutorial I've written about the same method:

http://www.makehumancommunity.org/forum/viewtopic.php?f=14&t=13734

I've done only one character (Dani) with an asymmetrical hairdo and the problem was the same in the beginnning. That is the reason why I put my hair-faces inside the character and rotate them. Furthermore I made these faces in overlapping order not to get big gaps. When you comb the character "deflect emitter" should be used, so that it is easier to comb an asymmetric hairdo. The hair tries to take the shortest way from left to right in your case. So may be a higher value helps. And the number of segments is also important. How many segments do you use for the particle system with the problem? Is it possible to create a polyline (a series of lines) with your number of segments to start on the left side and reach the rigth side, so that it looks good? Last not least, you can also edit each single hair, I've done it for the most critical zones, it was not simple :roll:

And now I hope for another good looking character :D

Yeah I've read your tutorial as well :)

I figured out what the problem was, the hair was clipping through the scalp. Idk how it took me SO long to realize.
Thanks for the help guys!
