How to fix outfit clipping on a VRChat avatar

Updated Nov 12, 2026

You’ve put a new outfit on and the avatar’s skin pokes through the clothes at the chest, hips or knees, especially when you move. That’s clipping, and with an outfit made for your base it’s almost always fixed in Unity, without Blender.

1. Check you used the right prefab

Many outfits include a separate prefab, or a separate shape-key setting, for each supported base. If you dropped in the prefab for a different base, clipping is the first sign. Check the outfit’s readme and make sure the outfit is on the list for your base.

2. Use the body’s shape keys

Bases come with shape keys (blendshapes) that shrink or hide parts of the body, often named after the area (Chest_shrink, Foot_hide), sometimes in Japanese (胸_小, 足首_隠す).

Select the base’s Body mesh in the Hierarchy.
In the Inspector, open BlendShapes on the Skinned Mesh Renderer.
Raise the values the outfit’s readme names, or try the ones for the area that clips, and watch the Scene view.

The readme usually lists exactly which ones to set. Some outfits set them for you.

3. Let the outfit do it: Shape Changer

Changing the body by hand has a catch: if you add a toggle to take the outfit off, the body stays shrunk. Modular Avatar’s Shape Changer fixes that by changing the shape keys only while the outfit is on.

Select the outfit’s root object.
Add Modular Avatar Shape Changer (Add Component).
Pick the body mesh and the shape keys to change.
Choose Set to set a value, or Delete to remove the body polygons under the clothes entirely.

Delete is the better choice when the clothes cover a part completely: the hidden skin can’t clip through any more, and the deleted polygons lower your polygon count. See the Shape Changer docs.

4. Still clipping?

Only when moving: it’s usually the thighs or the chest under tight clothes. Shrink that area a bit more.
Shoes: many bases have a shape key that flattens or hides the feet for shoes. Heels often need one to raise the heel.
A different base’s outfit: it wasn’t made for your body. Shape keys won’t save it; see your options.

Next: add a toggle so you can switch the outfit on and off in VRChat.
