PBRskin glossy not matching on grafts

I'm having trouble getting PBRskin to work with geografts.  (The effect is most noticable with Top Coat, but is present with Dual Lobe and normal Specular gloss.) The first image shows the body above the waist with PBRskin and below the waist with Iray Uber shader. Colors don't match, but the gloss does. The second image shows both with PBRskin shaders. Settings and maps are identical. This works fine with Iray Uber shaders. Any idea what's going on and if it's possible to fix it?

    Not sure what geo-grafts products that you use (anatomical elements ? a centaur body ?) ~~ Yes, the body and graft have to be with the same shaders but from the 2nd image, it tells me either the texture maps or the shader settings... or both are not really identical.

    If the geo-grafts are the anatomical elements from 3rd-parties, there're always scripts included in the product that can completely copy and set the material setting from Torso / Body to the graft. If it's the case, have you tried that ? or just manually configure the settings on surfaces?

    The geograft is a third party set of anatomical elements. There is a texture copy script, but it assumes Iray Uber shader and doesn't copy the full set of attributes of the PBRskin shader. I have meticulously checked the settings to ensure they're identical; the apply process was to attach the geograft, convert the shaders to PBRskin, and then copy/paste the shader. The only discrepency was the UV map; it appears that's stored internally as an index rather than as the actual name of the UV map, and the alternatives are not the same.

    Also, if I set the gloss on the PBRskin shader to ridiculous levels -- like, Top Coat weight 1, roughness 0 -- it still has no effect.

    Well, I own almost all AE products from 3rd-party sites, I haven't experienced such an issue by using Copy Material script, which firstly check the shader used on figure's Body\Torso surface, then apply the shader on graft's surface, then copy material settings.

    You may clearly tell the product's name, is it NewGen, GP, AP... or sth. ? Have you installed the latest updates of the product(s) ?

    I'm having the problem with both products by Laudanum and Meipe. I'm on the latest version.

    Well, I was having it. I had to reboot and now the problem doesn't reproduce.

    Turn it off and on again.

    Thanks for the help!

    Good ! NP ~ Sometimes it happens, so don't tweak them with Iray preview on...
