Hi Dartanbeck - I really hope you get the hair to work.
A couple of tips and tricks that seem to work for me:
* Increase gravity in the Physics settings for your scene to -500.00
* Only use carrara spheres for the collision objects - make sure the hair is set to
collide with nothing except the spheres. If the hair is made on a cap, make sure the
hair is set to not collide with the cap.
* In Hair Dynamics, try root stiffness 80%, Hair 10%, Shape 5%, Air Damping 20%, Density 1.0 -
If you want it to follow her body for simple movements, try increasing the Air Damping to 75%.
* For Segments per hair, you can use a high number like 50, but then check Override Segment count
and set at something like 12 Segments per Guide. The simulation will run pretty fast, and you can bump
up your simulation quality back to 100%.
I was able to get a decent simulation with these settings using Kink and Clumping in the shader, so
I hope it will work for your long hair.
I hope this helps!
Here is a quick video that demonstrates the difference between Air Damping of 20% and 75%.
