Hi Guys,

I'm getting nuts here. I'm playing around with different levels of subdivisions in UE and the standard Camila 4 character which works all fine.
I'm rendering with pathtracer and have done all the corrections to the eyes and tearlines. ..not visible to raytracing and so on:). But the dark lines under the eyes are still there.

It looks like the head mesh is casting shadows on to the eyeballs resulting in the dark lines. It's almost like the eyeballs need to be moved a bit to the front in the rig?!
Played around with different shadow settings in the light but with no effect:(

Running out of options in UE. Will try moving the eyes in the rig tomorrow to see if this has any effect. Maybe somebody has some other ideas?

Cheers,
Marcus

Yeah , I had this too , try to change the eyelashes shader (translucent) to mask.
Or deactivate the tearline ... I am not really sure what all I changed , will have a look when I am back in the Studio

Allready did all those ‘hacks’ :)
But none of them seem to have effect. So weird!

When I dissable the shadow casting of the keylight. The black border turns white. Same happens when disabling shadowcasting in the head mesh.

I’m almost sure it must be the shadow casted by the headmesh on the cornea and eyball. Will have another look tomorrow.

Cheers!

Now I know what I did, I had a custom CC Character with the same black edges in the eyes like you.
The problem was that the eyeballs had a little gap in depth and PT sees everything (like TonyDPrime 😁) and so PT adds shadows into the gap cos of light bouncing.
So you have to align the eyeballs in CC4 to get rid of the black edges and make sure your lids work correct in CC4 after aligning with the modifier "correct eyeblink".

And of course you have to deactivate "eye occlusion and tearline" in UE5 ... here they are activated for the left eye and deactivated for the right eye : 
You can use the MH Eye and Occlusion shaders for CC4 Characters too , sometimes they look better.
