Fit finished garments onto a new body. Without breaking them.

What it does

A complete fitting pipeline inside the Blender sidebar — no rigging, no proxies, no re-modelling.

Starter Guide

Your first fit in ten steps. You need three objects in the scene: the source body the garment was made for, the target body you want it on, and the garment itself.

1. Select your three objects

   Select the source body, the target body, and the garment. Make the garment the active object (select it last).

2. Open the sidebar panel

   Press N in the 3D viewport and open the Wretch AutoFit tab. Click Assign From Selection — the addon sorts out which object is which.

   

3. Create body profiles

   In Body Profiles, generate a starter profile for the source body and one for the target body. Profiles are JSON metadata (landmarks + soft regions) — they never store the mesh itself, and they're saved for reuse.

4. Check the landmarks

   Create landmark handles and verify the auto-detected positions. The detector measures the mesh to find the waist, hips, bust, neck, crotch, armpits, and limb joints — but manual verification pays off. Click Edit Landmarks (Interactive) to drag markers directly in the viewport; hold Ctrl to snap them onto the body surface. Save when done.

   

5. Validate the profiles

   Run profile validation. It flags missing landmarks and suspicious left/right or vertical placements before they can ruin a fit.

6. Set up the fit

   For a first try, keep it simple: enable Body Profiles, leave Body Shape Transfer at 1.0, and keep Body Hug and Surface Clearance off until the basic silhouette is right.

7. Create the fitted duplicate

   Click Create Fitted Duplicate. This starts Live Fit: a duplicate appears, fitted to the target body, and keeps updating as you change settings. The original garment is locked and untouched.

   

8. Tune while watching

   Adjust Fit Smooth if you see stepping, Edge Relax if the mesh stretches unevenly, and Surface Guide carefully (low values for loose garments). Then, if the garment should sit tighter, enable Body Hug; if it clips into the body, enable Surface Clearance.

9. Apply or cancel

   Apply Live Fit keeps the fitted duplicate — the result lives in its AutoFit_Result shape key. Cancel Live Fit removes the preview with no trace. If live mode ever gets stuck, Force Exit Live Fit in the sidebar cleans up safely.

10. Reuse your profiles

    Profiles are saved in Blender's user config under Wretch_AutoFit/profiles and can be exported as JSON for sharing. The next garment between the same two bodies skips straight to step 6.

FAQ & Troubleshooting

The fitted garment collapses into cleavage, armpits, or between the thighs.

Lower Surface Guide — for loose or semi-loose garments, 0.05 – 0.25 is safer than a hard body snap. The dense transfer already keeps loose fabric on a coherent regional envelope; Surface Guide should only nudge tight areas.

The garment still clips into the body, but collision is eating my wrinkles.

Lower Final Guard first. If clipping remains, increase Collision Passes or Clearance Strength instead of raising Final Guard, and keep Detail-Safe Collision enabled.

A sock or boot ends up offset or only approximately rotated.

The knee and ankle landmarks are the critical ones for lower-leg garments. Position and save left/right_hip, left/right_knee, and left/right_ankle on both bodies, and use Live Landmark Preview to fine-tune while watching the garment.

I want the garment tighter, but collision only pushes outward.

That's what Body Hug is for: it pulls the smoothed garment envelope inward toward the target body, then restores wrinkles and detail afterward.

Live Fit got stuck.

Click Force Exit Live Fit in the sidebar. It clears the live-fit state and removes preview duplicates — confirmed (applied) fits are never touched by this cleanup.

Can I just use bounds matching instead of profiles?

Only for similar bodies. Whole-body bounds are dominated by arm span, bust depth, and height, so one global scale can't preserve a finished garment across very different proportions. For Legacy ↔ eBody Reborn–scale changes, always use Body Profiles.
