NSFW version has additional content and switching

Why remove the original color toggle:Stocking color switching bloated the mod size. Including original color toggles would push the NSFW version to ~1GB. To save storage and reduce performance strain, original color toggles were removed—only weapon color switching remains (even I can’t take it seriously… what’s the point? ????).
Persistent genital texture mismatches in bright lighting:Likely a side effect of fixing the upper/lower body color mismatch. Editing 15 textures to fix it was too tedious—I skipped it (╯°□°)╯.
Minor clipping issues:With so many toggle options, clipping is unavoidable.
Why remove the semen in the NSFW version:They were hideous. Deleted.
Why no face texture toggles:Failed to extract face textures. Too much effort for minimal impact—gave up (┬┬﹏┬┬).
Regarding the persistent waist separation issue when selecting Vivian in the character interface: This is caused by miHoYo cutting corners during development. After discussions with several modders/developers, we concluded that a fix is virtually impossible due to technical limitations or lack of proper rigging.
【Tips】
f you are using xxmm, there may be character texture errors due to different hash values of the maps used for high-low rendering. Please use the repair tool ZZZ 1.7 Fix to try to fix it.If the weapon still has texture errors after using the repair tool, it is because you have low image quality. The repair tool will not fix the hash value of the weapon mod. Please find the hash value of the low-image weapon texture to replace it yourself.
