Is it possible to add hair texture to CS_Tools_3d stroke? Has anyone tried?

It looks like yes but you have to add the Hair to the SweepNurbs not the 3DStroke null. You could also make it editable of course.

Ok but you than lose the option to animation the Offset or well any of the Xpresso stuff. I guess the best way around that would be to transform from model one at a starting point to model two at the end point with Morph tag.

I’ve been playing with the settings. It is possible to animate the values if you apply the hair with the SweepNurb selected (you don’t have to make it editable that’s just one option) *but*
– the hair only will root where there is a positive thickness – an actual surface – if you get down to zero thickness (what looks like a spline in the viewport) hair does not root.
– if you animate the settings of the 3DStroke then render, only hair that exists in the first frame will render. Hair won’t ‘appear’ where the stroke gains thickness unless you hit the Update Guides button in the Guides tab of the Hair object, but that resets the hair to straight (or whatever the Dynamics rest state was set to with Hair/Edit/Set As Dynamics) and it has to fall again too.
– I modified the settings of the scale spline in the Details of the SweepNURB object. The various X and Y settings in the xPresso (CntrX, KneeX etc) are controlling the scale spline so I lifted the values of the ends of the scale spline (not controlled by the xPresso) so the Sweep always has some thickness (and can have Hair)
