Solved! - IRAY Uber Surface help please

Okay... So.

I have been trying to teach myself the surface tab of the IRAY uber base thing. BUT some stuff with older shaders just stays washed out with a white cast no matter what I do. I have read a few tutorials and watched a few youtube videos. (yes, sickle yield's) and I have removed all the maps and moved all the sliders but everything still looks washed out and I can NOT figure out why. Is there anyone out there super patient and super bored with a little time on their hands willing to walk me through this problem and help me solve it because I encounter THIS SAME issue over and over and it's driving me nuts.

For example... this hair below. You see in the preview it is brown hair. The texture looks like brown hair... but it renders washed out and grey.

Actually...any help at all would be greatly appreciated. heart

Thanks in advance smiley

    Which hair is it? Is it actually using the Iray Uber Surface (shader is shown at top-left of the Editor tab in the Surfaces pane)?

    It's Nimue Hair for Genesis 2

    But it isn't just this hair that I encounter this. It's with almost any older product that uses older shaders for 3Delight or poser. It just seems stuck on washed out and moving sliders doesn't change it much at all except to make it look like metal occasionally. I know it looks like I still have maps in some of the glossy tabs in the photo...but that's because I reset everything to take the image for you. after trying everything, like even using leather, velvet and canvas settings

    Try turning the specular settings down. April usually has some in the material options folder to make it easier smiley

    I promise you... I went through each tab... turned them all the way up...and all the way down. Moved white things to black tried all the weighted/spectular/metal options. Making the base tab darker does help...but... I want to set things with the actual texture and learn how to set the settings myself.

    It all makes total sense to me if I am adjusting something already using an Iray material setting, but when I try to update an old setting, this is what I have every time. Just really white and unable to get rid of it

    Shader is correct but just properties may need to be tweaked. Check Top Coat Color slot, see if there's a light color set there but with no map... If so, try to turn of Top Coat Weight, see if there's any change. Or post the full list of Surfaces properties...

    I appreciate the help...sorry it's taking me a minute to get the screenshot together... Please don't leave. LOL

    You haven't appled the Uber Shader it is still showing the 3Dlight shader. 

  • JasmineSkunkJasmineSkunk Posts: 1,906

    It just started doing that... That's what I was saying. It isn't the same thing I had before... See how it was?

    Now... I can't even get the Uber shader base to apply... I think I'm broken. I don't know how to fix me

    Okay I definitely broke something and I can't figure out how to fix it. I even uninstalled and reinstalled Daz Studio. Now the Uber base won't even apply at all.

  • JasmineSkunkJasmineSkunk Posts: 1,906

    What did I do? Now none of the Iray stuff shows in the preset window at all...

     

    And I see Feminine?? And Aiko??? what???

    I have noticed that many older transmapped hairs don't take to iray very well. You can try to use a tiled hair shader on it (something like this, which are my favorite hair shaders), but that hair in particular doesn't take well to tiled shaders because AprilYSH hairs all have different UV's. I know it's not the answer you wanted to hear, but I bought that hair a while back in hopes of converting it and never was able to get it looking good.

    Thank you everyone for helping so far... 

    I think I have it kind of working again... Though I have no idea how I broke it. But, it wouldn't even apply the Uber base. It is applying it now... But I am  so confused and frustrated at this point, I may just want to come back to this another time...

    THANK YOU EVERYONE! heartheartheartheart

    I haven't been able to do much with this hair, except by greatly darkening the base Colour which may not be what you want. Usually i woukld say turn down the various weights (to 0) until you eleminate the effect, then you know which ones to adjust, but that doesn't seem to help here.

    Thanks, for checking and confirming, RIchard. heart I really do appreciate it. At least I know it wasn't that I'm (just) stupid. lol laugh

    You're not going to believe this...

    I'm not even sure I beleive this. And I still want to tweak it - but on a whim, I tried something...and it looks like it WORKED!!  I remembered that Michael 4 has a "mapless" material setting, so I just selected all the hair and applied it. Here's how it turned out. I'll leave this here in case anyone else is having this trouble and I'll come back after I've messed with it if I can get it better...but right now, I'm happy. smiley

    A LOT of hair (cutout) opacity maps, new and old, are made of various shades of gray, which is NOT how it should be done. An opacity mask should consist of pure white and pure black values. There is no such thing as semitransparent, really. (Hello Vendors!!) Translucency is the way to go with transmapped hair, NOT semitransparent!

    Look! Not perfect but... Progress. smiley

    I don't understand some mapping of the braid, but overall I'm happy with how it's going.

    Thanks again to everyone who was helping!! Much love! heart

    Got it!!
    Ok in the surface tab click on the actual image that is being used as the diffuse map and select Image Editor, switch the Gamma to 0 and the hair goes back to the dark shade it should be!
    If you want a thicker look to hte hair without removing the opacity map click on the cog wheel on the opacity slider and adjust the max setting to around 5 or 6 then you can increase the percentage on the slider until you are happy with the hair's thickness!

    Ah, I had forgotten to check gamma - thank you.

    Oh, I'll have to try that! I remember Nimue hair not doing so great in IRAY because of its opacity maps, this may help.
