Strand Based Hair cut tool leaves stray hairs? Why?

satin.interfaces

I'm trying to learn this tool to make the most out of it.

I have done some haircuts, and come across this problem often. Whenever I cut hairs, there are some "stray hairs" left.

They don't seem to respond to the curves of the guide lines either, since they are so straight.

What am I doing wrong?

Thanks in advance!!

Perhaps a screenshot of the Style tab of the SBH Editor, showing all hairs and style curves would be more helpful, rather than a render, so that we can see what your guide strands look like.

I note that one side of your hair is long and the other is short.  Note that the length of interpolated (i.e., children) hairs will be influenced by nearby guide curves.  With your hair style, there may be guide curves nearby to the short hairs that are still long, such that the interpolated hair between them will be an in-between length, part way between the long and short style curves.  

If you cannot resolve the interpolated length issue then perhaps you can have each section of the hair as different grooms; one groom for the short side, one for the long side. In this way, hair length will not be interpolated across the different regions with drastically different lengths.

There is also a reduce length option under Tweak tab, which can be controlled by a map which you can paint on the Paint tab. If it is only a specific area with too-long hairs, then you could reduce length via a map.

Such a comprehensive repsonse! thanks!

It was what you siad, the interpolation. I tried what you said (separating hair grooms) and worked like a charm!.

Thank you so much!

Btw! I just realized you are the same person whose tutorials I am following online.

Thank you so much for sharing your wisdom! You got my respect, man!! Thank you really!!

This reflects my ongoing problems with SBH hair and dforce in general.

Sometimes perts of dforce items seems to flow randomly in space, defying the gravity setting.

Just very frustrating.
