YurePre | Fix Skirt & Hair Clipping and Tune PhysBones by Picking Presets [VRChat Unity Tool, Free Trial]

Skirt going through your legs? Back hair sinking into your body?

YurePre fixes it — even in the free trial. The trial really connects skirts and back hair to the body, not just a preview.

Why YurePre

• Free trial that actually works — Auto colliders and feel presets for Skirt and Back hair
• Two tools in one — stop PhysBone clipping AND pick the feel: Fluffy / Normal / Heavy / Firm
• Just $5 for everything — all types included
• Never touches PhysBones the avatar creator already set up, and "Revert" puts everything back

Auto colliders — stop clipping

YurePre finds the PhysBones that have no colliders, measures your avatar's body shape and connects them to the body.

PhysBones the avatar creator already set up are never changed. "Revert" puts everything back.

Just pick the feel

For each type — hair, skirt, sleeves, tail and more — choose Fluffy / Normal / Heavy / Firm, then press Apply.

Features

• Automatically finds PhysBones and sorts them into Skirt, Back hair, Front / side hair, Tail, Ears, Ribbons / accessories and Coat / sleeves / hem
• Choose and press "Apply" — no need to research a dozen parameters one by one
• "Revert" restores the previous values exactly
• "Shake test" swings the avatar left and right so you can check the motion right away
• English / Japanese UI

Works with outfits you dressed

PhysBones on outfits added with Modular Avatar are found and tuned too.

We confirmed the chosen feel survives the merge at upload time.

Auto colliders in detail (v0.2 free update)

• Skirt / coat hem → thighs (long ones also the shins) / Back hair → chest / Tail → hips and thighs
• Never touches PhysBones the creator already set up
• Reuses colliders the avatar already has, and only creates the missing ones by measuring the body (max 6)
• "Revert" undoes the connections and removes the colliders it created
• Works on Skirt and Back hair in the trial too

Minimal impact on your avatar

Changing the feel only edits PhysBone values, so upload size and performance rank stay the same.

Only when Auto colliders creates new colliders are up to 6 colliders added (uncheck it to skip).
