Hi tomas, Thank you for reporting this issue. We have identified this issue is a content defect. The material settings of some eye contents are improperly for digital human shader. There are two workaround for solving this issue: Workaround 1: Apply another eye content that can normally work with digital human shader. Workaround 2: Fix this issue with the following steps, 1.Copy Diffuse/Base Color texture of Std_Eye_R/Std_Eye_L to Std_Cornea_R/Std_Cornea_L (There should be no Diffuse/Base Color texture before you copy it) 2.Change Diffuse Color of Std_Cornea_R/Std_Cornea_L to White color (The Diffuse Color should be Black before you change it) The attached gif is a screen recording of workaround 2, please download to see it. I hope this helps. Irving Reallusion
