I get decent results out of P7, but the same dynamic hair comes out horribly wrong in P8, even with identical settings.  The hair density seems sparser, and the diffuse colours are washed out.

Anyone have any suggestions?

Just a wild guess: Have you tried "opaque in shadow" in the hair material node to see if it matters?

This was with "opaque" enabled.  I've tried it without, also.  Didn't matter.

Something has apparently changed in the way Poser renders the hair, and I don't think it's for the better.  Last night, I spent two hours tinkering with Firefly and material settings, and couldn't get anywhere near its original appearance.

I think the root width and tip width of the hairs has been changed.
Does it make any difference if you change that?

It appears to me like the light is reacting differently with the fur.

.......and both P7 and P8  have the same weird problem  of adding a black bar, with "censored" on it,  to  the hair.

Hmmmmmm.......

That appears to help with the sparseness.  Thanks for the tip.

That goes away when you enable raytracing.

After further trial, error, and profanity, I narrowed the main problem down to the image map node, when I discovered that procedural materials still rendered properly on the fur.

It's the texture-filtering option.  P8's texture filtering goes absolutely insane on image maps plugged into dynamic hair.  The results may vary with different maps, but the only solution I can think of is to disable texture filtering completely on those.

Here's the same #@$&% scene file in P8 again, this time with filtering disabled on the hair maps.

I'd considered that possibility earlier while troubleshooting, but had tone mapping disabled.

I've been tinkering with this for hours too since it's a disaster for my furred creatures. I can't "unplugg" the texture map since that is the key to my fur.
So how/what did you do? Pic?

 Ok, got it now. (Wasn't that hard after I started using my brain) :D
