Hello all! Does anyone know of a work around to get the tear line to show up in iRay? I just did a portrait of a character and noticed the eyes looked 'dead' compared to the native render. After closer inspection there is no tear line in the iRay render (along with other small things as well, but the tear line is most notable). Thank you for any help! 

Iray didn't support digital human shader.
Both of tear line and occlusion effect is acting on the digital human shader, iray material doesn't make an effect like tear line or occlusion.
Even if covert them to PBR shader ,effect in iray will not be right.
So that is the reason why they didn't make tear line & occlusion in iray to let us setting shader.
