Iray Skin Issue (LY Lisbet)

Hi,

I'm loading the iray skin texture onto the LY Lisbet character, however in iray render and preview, the joins between the different texture files (Arms, body, legs etc) are clearly different and showing up

I can't see anything obvious in the parameters to suggest one of the numbers is different on a colour aspect or anything etc.

If anyone has the issue or has seen this before?

Thanks

    Most likely one or more images has a different gamma setting - though I am surrpised it hasn't ben caught and fixed if so. Do you get the same if you use the character preset to get both shape and materials?

    Just checked, on a new empty daz file fresh load of the base character preset and it does have the same issue

    That's a pity. OK, in the Surfaces pane if you click on the nano thumbnail on the left-hand end of a mapped proeprty you get a menu (with the images loaded, Brows..., etc. - you may already know it). One of the commands is Image Editor (not Layered Image Editor) - click that to get a dialogue with various options, including the gamma value. It's probably the torso that is wrong, since it is different from each of its neighbours, so for each mapped property open the Image Editor on the map on the torso and the map on the arms and compare the gamma value - if they don't match set the one on the torso to the same as the one on the arms and see if that fixes the issue. One done, make a note of the problem so you can report it to support and save a new preset which you can use instead of the one from the product in the meantime.

    So I think i've found the image editor (dosplay the selected surface flat image, then has 'image Gamma' Type, instance Color, Scale, etc?

    If i'm in the correct place, it doesn't appear that any of the surfaces have a different value set.

    Image Gamma 0, Instance colour 1 across all ones with an surface image etc

    Are you checking al of the images - it could be soemthing to do with scattering or top coat too. It may even be a top-level property, I should have thought of that - especially as it is easier to check - select two skin areas in the surfaces list (Torso and arms) and then scroll down the list of properties - the map thumbnails will have gone, since the two surfaces use different maps, but the colour and numeic values should still be visible - if you see <?> for a value that means there s a mismatch, which would not usually be expected.

    Thanks, unfortunately the <?> check was one of the few I've come across before and had expected to be the issue.

    Likewise checked the other images too for the gamma stuff, no seeming differences I could spot.

    Looks like I'll just to put this one down as a broken set.

    Please do report it, though, even if you can't tell them where the issue lies.
