Yes.

You can't use dynamic hair outside of Poser :(

IF you have an older version of Poser (like 4, not even sure if this still worked in Poser 5) there's an easter egg you get if you type "hair" in the pose room (which was the only room in P4 L) That kind of hair could be exported with Masa's FurFur script thing.

But this is ages ago :) And the hair generated that way had insanely high polycount.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
