Problem with XGEN

#1

Hei!
I finished the grooming for my character, but i got a problem. Some hair are going super randomly and I would like to fix it. I have 2 clumping modifiers, and the problem seems to be in the attribute “Clump” of the second Clumping modifier. At the moment is set to 25, but when i turn it down to 0 the problem dissapear, but of course, the hair won’t look as I want. Is there a way to fix this?
Note: I did my hair as “Splines” not “Groomable splines”, I think if there was a way to transform the hair in groomable splines I could simply use the lenght brush, which I cannot use with the normal splines…Is there a way to do so?
I generate the first modifier through ‘guide’ and the second one with ‘generate’
These are the things I already tried to fix the issue:
1)Delete the second modifier and create a new one with the same values.
2)Deactivate the second modifier withouth deleting it and create a new one with the same values.
3)People suggested me to have the density of the second modifier at least 3 times bigger than the one of the first one, but it sounds strange to me as for the firs modifier i create the hair through ‘guide’ and not ‘generate’, so the parameter density shouldn’t affect the first modifier. Anyway as by default the parameter of the first modifier was at 1 I tried to put the density value of the second one at 3. I tried even different values, from 1 to 50, the bigger the number the more the problem dissappears, but the hair starts to llok like the second modifier is not even there if I do that.
4) Try to open the file on another pc to see if it was a problem of my maya
5)Change the order of the 2 clumping modifiers, making the second one as first and viceversa…

Hi TheCrazyLost,

I too have the same problem with this every now and then (unwanted stray hairs).
The way I fixed it (which is usually a hit and miss) is delete the guide that is making that unwanted stray hairs.
Then re add it again but slightly offset on the original deleted guide.

So basically it is,

  1. Identify the guide that is causing the stray hairs
  2. Back up that guide. (Perhaps as a curve then nudge the source a bit so it is in a different origin than the first one).
  3. Delete the old guide.
  4. Readd the back up/new guide.

Correct me if I’m wrong but are you doing the big hero 6 hair style? If so, am I correct to say that each clump of your hair represents one guide?

Really thanks for the quick answer I’ll definitely try it now.
Well yes, I’m not only doing his hair style,I’m completely re doing him…Btw yes each clump is a guide :slight_smile:
