Ok let's get some details out first.

Victoria 4 - using ezskin3 for the base setup

This does NOT happen in poser 12.

I can take a Poser 12 file without it happening, open it in Poser 13 and it happens.

there are weird blow out to white spots happening to select jpg textures in poser 13's scatter node.

Below is the Poser 12 render...

then below is Poser 13 -of the same exact file

I'm not worried about the brightness and skin, my problem is the pupil/iris.

At first, I thought it was picking up some reflective white surface, but after pulling out a lot of hair, I discovered if I just used a different texture it would go away.

then I noticed this in the material room...

WEIRD blowout spots that just happen to be exactly where the spot is on her eyes....

but if I plug in a different texture...

I thought maybe there's some difference in the color settings of the jpgs... but I can overlay the "bad" one over the "good one" in photoshop and make a new jpg that still acts weird.

SO- for now I can just find another texture that's close enough as a workaround... but I'd really like to find out what the culprit is and how to fix it.

Thanks!

Change the Scatter node SubsurfaceMethod to RandomWalk or RandomWalk fixed and re-render.

 I have it doing the same thing on some skin textures. That's not supposed to be white on the eyeshadow.

Suggestion, plug the problem diffuse map directly into the Scatter Node and note if there is a difference.  Also, change the HSV node for the HSV_2 node, that's the node you should be using as a replacement.

BTW, Firefly or Superfly?  You did not specify which render engine you are using.

I did try plugging the map directly into the scatter node - it still had the problem.

the most curious thing is - I can find other textures that work just fine.

if I could figure out why some textures do it and others don't... and it was something I could alter on the offending textures... I'd be all for it.

In comparison with the images you provided, there shouldn't be any reason, under the same set of conditions, that one set of textures works and the other doesn't.  There are a good number of users that are shying away from EZSkin and conforming to using the PhysicalSurface node or Cycles node for Superfly rendering.  Snarly is considering revamping EZSkin to use the current Superfly alternatives, I'd be willing to test run the prototypes. 

Ghostship has created Superfly-specific eye shaders for V4 and, IIRC, you should find them in the free section.

I just tried saving one of the jpgs that acts up as a Png, bmp, PSD... they all still do the same thing

I've seen this too. I had meant to investigate it more and then post here to see if others have seen the same issue, then report it as a bug. Unfortunately, RL has been a bit crazy lately and I forgot. And it's not just on Vicky. It was either M4 or L'homme I was working with.

I think the old EZScin3 mats are a little off in P13. I have a SSS skin thread in the P13 forum with examples and mat room materials

I did some hunting this morning

These scatter nodes seem to be the problem. They turn any pure black to white. Changing any of the settings in the nodes does nothing to help. Change the black even the slightest and it works again. You can edit the actual image or you can use a mix node to make it work.

that was the lowest blend I found that worked... if I added one more decimal it failed.

Well that completely bites!!  Hopefully, the techs can integrate the patch into the new release coming out soon.  Someone did submit a ticket, did they?

If you are using Cycles nodes, this would be the arrangement:

I am creating a ticket on this, linking it to this thread.

I used to test for Poser on the Smith Micro team.

eons go

didn't you have a bunch of freebies here at Rendo a long time ago? I seem to remember some superhero stuff of yours that I downloaded.

Thanks, but I'm a bug magnet, but not a bug fixer. :P
