SnugFit Lite - Free Fix for Skin Poking Through Clothes

SnugFit Lite is a free Blender add-on that fixes skin poking through clothes. Select the outfit, select the body, click Fit: anything inside the body is pushed out to a small gap, and the folds of the cloth are kept.

• Fit: anything inside the body is pushed out to a small gap (2 mm default) and the push fades over the cloth around it, so folds move instead of getting ironed flat
• Saved as a shape key named SnugFit, so you can dial the fix back
• Two-way check: catches body detail poking out between the vertices of a low-poly outfit, which Shrinkwrap misses
• Clip Check: scrubs the animation and reports the worst poke-through in mm and its frame
• Quick Start: one click adds a torso and a shirt that pokes through it, ready to fit

1. Install: Edit › Preferences › Get Extensions › Install from Disk, and pick the zip.
2. Press N in the 3D viewport and open the SnugFit tab. Click Add Demo, then Fit.
3. On your own scene: select the outfit, shift-select the body, press Fit.

• Raise Falloff if a push leaves a dent in the cloth; lower it to keep the change local.
• Mark vertices that must not move (waistbands, collars) in a vertex group named SnugFit_Pin.

• Demo shirt: 1,002 vertices too deep and 310 body points poking through → 0 and 0, in 0.1 s

• Blender 4.2 LTS to 5.2; Windows and Linux tested, macOS not tested
• One outfit per Fit; fitting is done in the rest pose

Lite stays free. The full SnugFit is a separate paid add-on; search SnugFit under Add-ons here on Blendkit.

• Layers: tights + skirt + jacket fitted together, inside-out
• Fit to This Body: move an outfit made for one body onto another
• Transfer Weights and Transfer Shape Keys from the body
• Hide Body Under Outfit: masks the covered skin

Remove Lite before installing the full version.
