Question How to efficiently process UVs exported to blender？

[vvs123]

I am trying to import the character model of VAM into Blender, but after using Daz importer to import it into Blender, either the low sided model has UV but no genitalia, or the high sided model has genitalia but no UV. I can only change the texture once now. Is there a more efficient way to obtain a model with both genitalia and UV?
