Roxie isn't widely used - that's probably the reason you were unable to find anything about that.

I'm loading her here to check.

This is the material of her corneas:

Expanding those nodes:

I'm going to assume you have no knowledge of building materials in Poser - if you do know about it, please ignore most of this, it might help someone else.

Okay, so a number of things:

If you have a lot of bright things in your scene, that Reflection_Value of 0.7 (under the main PoserSurface node) is way too high. That makes her corneas almost a mirror. Lowering that number may help. (I also have no idea why they plugged it into a Blender node with nothing else, AFAIK that does nothing, but whatever.)

In general, that Blinn node seems too bright for me as well. a Reflectivity of 5 feels like something more prone to highlights than anything in nature - I'd lower that down to 1 or less than that.

And keep in mind that Roxie has a material zone for each of her eyes, so you'll have to change the material in CorneaRight AND CorneaLeft.
