Problems with OOT Hair - *Finally, Probably Solved* (12 May 2023)

jrobbit_323250f625

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..

Happy render to all of you...

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.

So after a couple of weeks and with some additional testing... I'm 99% certain that Nvidia's vMaterials shader set is/was the cause of all of my troubles. In both Daz Beta and Daz Current Release, downloading and installing those shaders is what caused everything to go wrong, and deleting all of them is what caused everything to "go right" again.

Deleting all of the vMaterial shaders appears to have fixed both the "OOT Hairs render black" problem and the related "parts of UltraScenery render black" problem. I was working with Nvidia's Version 2.0 and 2.1 shaders at the time. There's a Version 2.2 that has come out recently, but I'm not going to touch that with a 2.2-meter pole! 

Many thanks to Richard, FenixPhoenix, and everyone else for their help and support. Let's hope that this is the end of this thread! (well, unless/until Nvidia and/or Daz breaks something else...)

And how did you unstall or delete those vMaterial shaders?
