Help Please: Weird Rendering Error After Changing Light Settings

in Technical Help (nuts n bolts)

So I had a scene building up: a single Genesis 8 figure, and some point lights. I decided I didn't like that, deleted or hid all my point lights and switched to FWSA Soft Light Probes. Suddenly, my character's head has this weird thing going on in the render:

https://sta.sh/0202z0jmdxet

All that weird redness isn't supposed to be there. If I hide the hair base totally, it goes away. But, if I do not hide it, yet turn all the opacity sliders to zero, it still does this error. Even when I set my scene to "scene only" lighting or "dome and scene" OR just dome, all three times this ugly thing renders. And I have never had a problem with the hair. It MUST be the lighting... what gives? Is this product broken or is something else happening?

Unreleated but also annoying: Her eyes are suddenly not fitting into her head and I don't know how that happened, either.

    I took a look at the picture, but where's the redness exactly?

    It looks fairly normal, I assume the Light Probes are mesh lights which can take a fair amount of time to render. What kind of GPU do you have? Try increasing the Render Quality parameter and do less iterations (samples), that sometimes speeds thing up.

    By taking away 'physical' lights did you, by default, then enable the headlamp on the camera?

    I'm not seeing redness either.

    What? That has *nothing* to do with my problem.

    Don't you see that ugly band on her head? That's what I'm talking about. It may look quite black, actually, but red on the edges where light is hitting it better--maybe that wasn't so clear. IF I have this issue again I will be sure to post what it's supposed to look like, too.

     

    Simon, good point! Maybe that was the issue, I'll test it out. Unfortunately that didn't work. :(

    What redness?

    Have you ever calibrated your monitor? If you don't know what I mean, you're not seeing the colours as they should be. How much off they could be, varies from monitor to monitor.

    Skull cap with wrong transparency map possibly.
