Hi xxx Thanks for your Feedback, The "High" option will only appear when the character's Skin Texture is 4K. You can convert the character's Texture to 4K from the Modify Panel / Appearance tab / Skin, and then try again. There are relevant teaching links below : https://manual.reallusion.com/Character-Creator-4/Content/ENU/4.0/15_SkinGen/User-Interface/Skin-Gen-Editor-in-Appearance-Editor.htm Thank you for your help.
