I don't have a lot of time to fiddle with Poser 7s guts; so I bought the [Real Skin Shader](../../mod/bcs/index.php?ViewProduct=33382) and tried it out on an existing, working render.

Mostly it worked, but has these strange white "outlines" in places.  Can't figure out why.  Changed a few settings on the script - different reflectivity, different lights. Same or similar results.

Hoping you experts can supply a simple solution.  As I said earlier, too busy writing and earning a living to fiddle with complex settings much.

Please help.

Figure is V4 using Lara by RMTH.  Lights are by Battle Lights by Lightworks.  Rendered with Poser 7 firefly.

Someone suggested it might be some kind of AO problem - but they also suggested I come to a forum with a wider audience.  (So, here I am.)'

Thoughts?

PS - Is it just my browser(s), or is the FAQ link on the RSS page not working?

Might help someone help you if you post your render settings.

Here's my guess.

You have a light directly behind her head and shadows are not enabled for this light. Light is leaking through and illuminating her face.

The reason is that RSS (and any proper skin shader) implements Fresnel specular reflection. This means that you get strong specular effects when the light hits the skin at a very shallow angle of incidence. When you set up a light like this it's called a rim light, because it highlights the rim of curved surfaces.

This is usually desirable as it is realistic, but not without shadows enabled.

So enable shadows on the rim light.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

It's the Poser standard settings with the bar pushed over to the "final render" setting area (just before the end) on the right.

Didn't fiddle with anything else.

That's possible.  It's an out-of-the-box light set, so i haven't changed anything on it - but I certainly can check that.

Thanks.

If you want to see the original render, without RSS, there's a wallpaper version here:

If that helps for future advice.
