The problem shows up with trans-mapped hair in a mirrored reflection, oddly enough higher mirror quality seems to make it worse, if anything.

Texture filtering was off, as were all the other options on the right side of the Firefly setting box.

Any ideas, other than fix it post work?

Kozaburo had a tip for P5 rendering on his site.  It's probably still there, but I haven't been there in ages.  I seem to remember that he recommended texture filtering when having FireFly problems.  Haven't tried it because I haven't run into any problems yet.  I hope that's the fix.

Poser 6 has a bug in it in regards to mirroring transparent objects.
I e-mailed E-Frontier about it. They had me send them the PZ3
file so they could look at it.  They acknowledged there
is a problem but had no solution.  In my case it was the
eyebrows that looked funky. But in that Koz's hair depends
on transparency maps too, this is going to happen there too
and apparently there is nothing that can be done about it.
I'm not sure if SR3 fixed it or not, but I didn't see that
problem listed in the items SR3 is supposed to fix.

Yeah, it looks like maybe it is really a bug, nothing you can fix.  I just tried texture filtering, no improvement.

Same really, I'm going to have to figure out how to render in DAZ Studio, I guess. 

Thanks, though!

You need a prop to reflect for the transparency to work right. You may need to turn on smooth polys to reduce the culling error.
Are normals forward checked in the hair materials?
