Quote - Some hair makers have the display setting hard coded in, I believe.  So, checking "Texture shaded" makes no difference.  IIRC, some of Koz's hair is like this.

 Certainly the element display style is normally coded into every actor in a cr2, and the overall figure display style is also specified in the cr2. However it's not "hard coded", you can always change the Display Style via the Display Style palette.

You should remember that there is a 'Figure  Display Style', and an 'Element Display Style', and you may need to set either, or both, to get the desired style. I'm not knocking RobynsVeil's advice. Of course if you want to fix it permanently at the source, edit the cr2. But for those who may not feel comfortable editing Poser files, just use the Display palette.
