Material rendering that reads true

Fabric Surface Fix API

Repair fabric texture, weave, and material rendering on AI-generated apparel. Denim that looks plastic, knit that looks painted, leather that looks like vinyl, silk that lost its sheen.

How it works

No pipeline to build, no models to configure.

1

Send target + fabric reference

POST the garment photo plus a reference fabric swatch or close-up of the correct material.

2

AI rewrites the surface

Reference-guided inpainting rewrites the garment surface (skipping logos, prints, hardware) with the material signature from the reference, relit to match the scene.

3

Get accurate-feeling output

Receive the photo with denim that reads as denim, silk that reads as silk.

Material signature from a swatch

Send a reference fabric swatch or close-up and the API rewrites the garment surface to carry that material's signature: weave, gloss, pile direction, transparency. Generic models render a generic 'cloth' surface. Fabric Fix renders the right surface.

Weave, gloss, pile, and transparency preserved
No fabric-type drift across the garment

Skips logos, prints, and hardware

Auto-masking excludes logos, prints, and hardware from the rewrite, so brand marks and graphic prints stay untouched while only the fabric body is corrected. Combine with Logo Fix and Print Fix for a full QA pass.

Lighting-matched output

Reference fabric is automatically relit to match the target scene's lighting direction and intensity, so the corrected surface integrates with the garment instead of reading as a pasted patch.

Fabric Fix for every material-forward category

When material is the product, the surface has to be right. This is the layer that gets you there.

Premium apparel brands

Silk, cashmere, leather, and high-end denim live or die on material rendering. Fabric Fix corrects the AI artifacts that drag premium garments down to mid-market.

Denim and leather brands

Texture is the entire identity of denim and leather. Generic AI rendering flattens both. Fabric Fix restores the surface signature.

Knitwear and wool

Knit pattern and wool texture are the most distorted by base generation models. Fabric Fix is built to handle them specifically.

AI fashion platforms

Add Fabric Fix as a polish step in your generation pipeline to ship higher-quality material rendering without retraining your base model.
