    And now I've run into even more weirdness with the combination of Ghost Lights and the Jolina Hair. Arrrrrrrrrrrrrrrgghhhhhh!

    It isn't just the skull cap any more! (Maybe it never was, and I just had the wrong angle of view or wasn't noticing this [new?] anomaly I've now run into, while placing cameras for an animation in the scene.) I am attaching three renders:

    1. Rendered with TWO of KindredArts' Ghost Lights: one horizontal above the girl (neutral color), one vertical to her left (camera right, an orangeish hue, as earlier in this thread).

    2. Rendered with the vertical camera left Ghost Light (camera right, her left) turned off, the horizontal one above her left on.

    3. BOTH Ghost Lights turned OFF. Also the lagoon object in Lagoon Living turned OFF (Girl is way too dark with it visible). Lit just with the interior Lagoon Living lights on, plus the basic dome lighting--AgentUnaware's 002, infinite dome, Dome-and-Scene setting.

    It's plain to see that weird bright red "ghost" of the hair over her left breast in the first one, with the her-left vertical Ghost Light on.

    It's much better in the second shot with the overhead horizontal Ghost Light on, the vertical one off, but it is hard to tell for sure because it's so dimly lit.

    The last shot is, I think, a reasonable representation of how the hair should look in a render, even with some very fine strands visible.

    But I've got to have some kind of added light to this scene (with the "lagoon" turned on) or the girl will be almost a silhouette!

    Since nobody seems to understand what is causing this haunting of skull caps and electro-glow hair bits, does anybody have any suggestion at all of how I can light this girl and her immediate surrounds--without it blowing her out so much that she looks, herself, entirely like a ghost? I can't lose any more time trying to make the Ghost Lights work.

    EDIT TO ADD: I've solved this for my immediate purposes by duplicating the horizontal Ghost Light, moving it over to her left and angling it a bit. Now there are no radioactive hair bits on her breast. But somebody on the technical side really should figure out what is causing this beastly behavior. The only common denominators I can identify, at least with this hair, are the vertical Ghost Lights. That's what caused the skull cap to glow through on one side, and made parts of the hair go radioactive on the other. I hope KindredArts will find it worthwhile to wander back this way again.

    it seems to have gotten worse for me. Am getting it even near 0,0,0 on both optimise settings today.

    Do you have any screen grabs of what was happening when you posted this? And can you tell me whether you had any vertical Ghost Lights in the scene? My problems with the skull cap, and with the "radioactive hair," disappeared when I deleted both of the vertical Ghost Lights I originally had in the scene, and replaced them with two horizontal Ghost Lights, positioned above and in front of the character, angled down toward her.

    I'd be very interested in knowing the details of the lighting setup you had when you got the skullcap problem, "even near 0,0,0."

     

  • I know this is a very old post, but if all the parameter changes and setting the world to the zero coordinates didnt help, here was my solution: I had a vehicle situation and applied hair to a passenger who was looking out the window. Then i added a ghost light and together with the environment lighting i rendered. Then I had this exact skullcap problem, although mine was a lot more subtle. Then i've put the ghost light directly infront of the door window (inside the vehicle) and the problem was GONE. It appears the skullcap has problems when having multiple light sources that travel through material, like glass in this instance. Hope i can help someone after all this time! :)
