So taking all the feedback into consideration, I saved out a separate scene, deleted my imported fiber eyebrows, and started over again in the hair room.

Right now, I have some eyebrows that I am fairly happy with.

The only issue is that there is no taper to the shape of them at all. The fibers were grown directly from the model polygons and thus, the eyebrow shape is rather blocky.

Is there a method I can use to create taper, i.e., in my preferred modeling program I could use a weight map to control the length and volume of the fibers, or even visibility if desired.

Is there any method similar to that to control fibers in Poser Pro?

Thanks for all of the advice!!
