Hello there everybody and thanks for reading my question!
I imported the base model from CharacterCreator4 into Blender using the CC/iC tools addon and customized the proportions of the character using sculpting. I did not add any extra geometry neither remove any existing geometry but when I'm trying to reimport the model into Character using the Blender pipeline addon as shown in this video

Can someone please help me fix this issue?
Thank you very much!
