Genesis 8 female Hip deformation error
I don’t know if a certain deformation product is loaded, which causes the Genesis 8 female’s buttocks to be loaded incorrectly. And Genesis 8 male buttocks loading is normal
I need everyone's help, please help me.

That morph is the "Hip panyhose" in your parameter's tab. Type in "hip" as a search and you will find it. Click on the gear and select "reset value". That should correct the problem. The bigger question (and I don't know the answer) is why that morph is acting as a default when you load the Genesis base character...
Does this happen when you are adding a new G8 character to a scene, or when opening the same scene up? Do you have the "hip pantyhose" morph saved as locked?
It could be the SY Decrackifier.
I'll try it
