I mean this problem, please help me.
This isn't an incompatibility issue of the figure, just that there's no textures for the genitalia. It happen often, probably less than 50% of the models include genitalia textures. There's many way to solve this issue.
You can try to tweak the New Gens texture itself, starting by a lighter "Base Color". You can also browse the other female figures you have, until you find one with genitalia and skin color near to the one of Aurora. May devs do that, but please, try to edit the texture to make it as seamless as possible. Or you create the texture by yourself.
You can also keep the Aurora figure morphs, but use the skin of another figure, one that include genitalia.
