Genesis "Basic Child" character rendering BRIGHT PURPLE for me in IRAY

in Technical Help (nuts n bolts)

Okay, I've gone into People > Genesis >  Characters, loaded the Basic Child character and started a render in Iray engine.... and he's coming out bright purple, even though the character is showing normal skintones in Viewport.  I've also tried applying !Iray Uber Base onto him, I've reloaded the character and applied RiverSoft Art's 3DLight to Iray Converter (which, oddly,  messes up the texture allignment on this character), but no matter what I do (other than render him in 3DLight engine), the character renders bright purple.  What am I doing wrong?  0o

    It probably changed the UV Set used on the surfaces.

    I just tried a test render and didn't have this problem. Which version of DS do you use?

    "Basic Child" migth come with a custom shader I think Riversofts can't handle custom shaders, so if the character uses such it will probably not be good.

    But what happens if you aplly Iray Uber base? Does the surface settings change to Iray, or isn't there any change at all?

    Edit: I just tried myself, and applying Iray Uber base works fine and it renders ok. I think I would try repeat the proces and have a look at how the surfaces look.

    I'm on the current, 4.11 64bit version of DS, last night I simply went and loaded the Basic Child character directly from the Genesis Characters folder (i.e. didn't load him over the top of  the unmodded Genesis character), and he loaded with the appropriate-looking fleshtones.  Went straight to render, and he came out bright-neon-colored.  As an experement I selected the feet surface in Surfaces, applied !Iray Uber Base onto that, and in the viewport the feet changed ever so slightly in tone but kept the fleshytones.  I clicked Render again, and that part was still rendering bright-neon-colored like the rest of him.  I deleted him out of the (empty) scene, loaded him again, ran the 3DLight-to-Iray scripts on him (which I'd tried earlier only to see the textures go a little screwy, got the same results this time), clicked Render... and got the same bright neon color.  Wierd thing is, I also tried loading one of the other Genesis characters I have in there, YT Justin, placing him down next to Basic Child, rendered both... and Justin came out normal looking while Basic Child still came out bright neon.  Looking at the surfaces right now for YT Justin, they're clearly in 3DLight format/legacy format, same as Basic Child (tho with different shaders).  On the other hand, scouring through all the surfaces for Basic Child, I don't see any color settings in there that suggest bright purple.  Having loaded them fresh today, in Basic Child see a Scatter Color set to red, though, Specular Color set to a dark black, and several other things set to white, grey, or to a very slight grey, but nothing remotely close to purple.

    Dunno what's going on here, this is driving me bananas.

    Weirdlaugh. And if you load the Justin mat onto the basic child?

    Edit: I'm on 4.9 so for what it's worth, basic child renders fine with default settings.

    It is the DS default shader;)

    Incidentally, is it at all possible that something I installed into my Content folders could have altered something under the hood that makes the colors on this character come out wrong?  And if so, how would I detect what it was?  I know that occasionally morphs spontaenously turn themselves ON for other content when you install some new character that includes a special-made morph for the just-installed character.  Could similar things happen with shaders?  0o  I suppose I could go look at the appropriate shader files for the Basic Child character and see if the datestamps on them changed or something.

    Okay, I've tried some more experiments on this... and it seems if I load the Genesis base character, and then apply any of the Genesis Materials that are in the root of the Materials folder and that have regular skintones on them, but that have a wetsuit baked into the skin, the wetsuit shows up as the expected color, but the bare-skin portion renders bright purple.  (The Neutral Grey material shader renders to a light, light grey that looks closer to white to me, but is probably the intended grey.)   I've tried at random several of the skin shaders in the subfolders (i.e. in David 5) and they're all rendering to the expected fleshtones. Could something have been corrupted in the GenesisStarterEssentials stuff?  Or in something related to the rendering engine on my system in a way that's only being tripped up by these handful of Genesis 1 shaders?

    Just to be clear... when you say shader, you mean material preset, right? The name of the shader is in the upper left corner of the surface editor tab (DS default etc).

    I'm shooting in the dark, but if you load the basic child that comes with the DS default shader, if you select, say torso and look at the lighting model, it should say skin, that has a very simple scatter model, what if you change it to plastic and render in IRay? Still purple?

    And the skins that render normal, which shader are they using? DS default, AoA SS, other?

    Yeah, I was talking about the Materials presets.  Anyway, I've just tried uninstalling and reinstalling Genesis Essentials under the theory something got corrupted in there, but its not made any difference, Also, changing the Lighting Model dropdown from Skin to Plastic makes no difference wrt the purple color.  To compare it then against the other things mentioned, I just applied the David 5 All material preset, and there doesn't even seem to BE a Lighting Model in there to try changing out, nor does the Freak 5 All materials base, or do the M5 Phillp All presets, or many of the others.  Hiro 5 Base materials preset is already set to Plastic, so are the presets in the Young Teens 5 folder.  All of those others render as regular fleshtones in the iray engine, but all the Sample character material presets render purple instead of skintone.

    This is on DS 4.11 64bit running on a 1060 card on Win10 Pro 64bit.  Anyone else with the same specs try this?

    DS4.11, 64bit win10pro and a 1060 here also. Loaded the basic child (which loads by default with the 3dl materials), rendered with the default Iray settings and no problem..... 

    (The lighting model you mentioned is part of the 3DL shader, and not used by Iray. When rendering in Iray, DS converts 3DL mat.settings to Iray as best as possible.)

    Weird, to say the least.....

    Looks like ticket time!

    Would be interesting though to know what happens if you load a skin that works with IRay, then manually load the maps from the basic child skin...
