If you're worried about the hair not rendering in other apps try this:

Open Poser 4 Pro Pack, load the ball prop into the scene, select it and type "hair" into the keyboard.

Create a hair growth on the ball and save it as a pz3.

Open that using the Lightwave or Max plugin and see if it renders.

The treemaker hair has the same construction as the P5 hair, only P5 adds parameters so it will render.
