This problem is popping up again but with a diferent character, I use the Natasha character from Reallusion. Here is a path traced render with native OV sky hdri environment dome light:
This is the Redhead huntress model, that is also shown here earlier, when we thought this case was solved. I double checked the results with this model ( based on the CC female preset called
@pekka.varis
White lines appear when Shader > Subsurface Scatter Scaleis set too high,
or when an improper SSS map is used, such as a solid white texture.
You can check and adjust the settings in iClone first, or do the chagnes directly in Omniverse.
In Omniverse: Reset Subsurface Advanced > xxx_Scater_Scale to 1
In iClone:
Double click the sliders to reset to default
But still there remains that white bright line around the eye area.
In the eye or eye occlusion materials there was not this scatter scale 1.25 to change.
How do I fix this? @WendyGram could you send this so someone in Nvidia who work with the CC USD settings. The Natasha CC characters face skin Shader > Subsurface Scatter Scale must be set to 1.0 not 1.25
@pekka.varis
for path-traced SSS with bright HDRI
I think you could send the most recent USD files to @WendyGram
and @WendyGram maybe ask for Omniverse RTX render experts like Morteza, Frank Liu, to take a look if they have time?
Not bad! I cannot see those white line rendering errors anymore, not is skin or eyelines! Also the SSS skin values at head material values are all correct, 1 and not 1.25.
Sometimes applying the white texture as SSS map in iClone is for better SSS result, but it is very easy to cause white line problem in Omniverse. (Natasha’s SSS Map is whole white texture, please reset it.)
If you have alrady executed Reset Texture for SSS Map, but still has the white line problem.
Please try to decrease Subsurface > Scale in Omniverse.
