(Shown above: SreeD display engine) Hair props that show up in preview as semitransparent.  The document, figure, and element styles are all texture shaded.  With the SreeD display engine, the hair previews accurately.  But with Open GL it shows as semitransparent.  I have the current drivers for my video card and also loaded SR3 for Poser 8, where the same situation occurs.  These examples are shown in Poser 7.

Note that in the material room, the texture map gets substituted for the transparency map.  Even if I load the transparency map manually, it changes immediately back to the texture map.  In the advanced view though everything looks fine.

The hair renders fine, but it's hard to adjust it when you can barely see it.
