My Solution: I use 3dlight-Colores instead of the Iray-colors. Then I use for the colors the converter from 3dlght to Iray with "DAZ-Uber" - and there is no more any Problem to render..
Okay, here's one more for fun and it may have revealed something interesting?
(1) Load the base Lainey Hair;
(2) Add OOT's "Hair Base Material";
(3) Select all parts in the Surfaces tab and apply the basic Daz Iray Uber Base shader;
(4) Go back to OOT and apply "Lainey Hair Color Base 8/Iray" to all of the surfaces;
(5) Success... sort of. At least it renders in a color other than black. The biggest difference is that when you go to the Surfaces tab, the Shader is listed as Iray Uber (MDL) instead of OOT Hairblending Hair (MDL). The latter adds Top Coat options and several Overlays, so those might be where the problem lives (however, playing around with them didn't seem to cause any change in the all-black appearance)
thank you. after weekends of installing and reinstalling OOT content, mapping content, mapping materials, reshuffling material orders, combinations of nvidia mdl files, updating Studio, rolling back Studio, rolling back GPU drivers, and I can't recall what else yours are the only steps that seems to fix it.
