Thank you, for your time, I really appreciate it. I will check it out.

Thank you for your interest and time, I appreciate it.

Here is my hairstyle scene: 10439_splinehairdisplacementanimation.c4d.zip

Thank you, I really appreciate it. Unfortunately your scene doesn’t not work:

1) the hair is not distributed between / around the 4 lines created from the edges of a cube

see my screenshot when I open the scene:

2) the hair animation/movement is not driven by the displacement texture noise, but by dynamics being enabled. When I switch them of nothing moves

3) in your scene Hair Guides Roots are set to ‘Spline 2D’ and Hair Roots to ‘Auto’. That’s not what I need, maybe that’s what causing problem described in point 1) see the screenshot above. For my hair styles to work I need Hair Guides to be set to ‘Spline Guides’ and that Hair Roots set to ‘Spline 2D’ to get a good hair style.

Sorry for the delay in communication, things are crazy over here, I am under a tight deadline.

I checked out your sample scene – thank you, it’s helps rule out a few causes of the problem.

The big difference is in the Spline I have: it’s created from a mesh, by selecting a lot of edges and than using Edge to Spline = it’s one spline objects with hundreds of fractured lines, see screenshot. So the only way to even have a nice hair distribution is to use Hair Tab > Roots set to Spline 2D:
– but even if I set my scene to Auto it doesn’t works
– when you scene is set to Spline 2D it doesn’t work either

I tried to start from your sample scene and do the following:
– create a 2nd Helix, shift it a little bit
– convert both helix into 2 splines
– select both and use Connect Object + Delete to create 1 spline, that is build form the 2 Helix shapes
– use this 1 new Spline as the Hair Guides Link object, set it to Spline Guides, set hairs to Auto – the Hair distribution is ok, but the dispalcement animation doesn’t work
