# Material Metamorphosis: rebuild one object in a new substance

Transform the material of one chosen object while preserving its form, function, environment, and physical interactions.

## Prompt

```text
Use case: localized material transformation
Input image: the attached image, containing the object to transform
Target object: {{target_object}}
New material: {{new_material}}
Finish and age: {{finish_and_age}}

Primary request: Rebuild only {{target_object}} as {{new_material}} with a {{finish_and_age}} finish while preserving its original form, scale, position, and function.

Material logic: Model realistic density, thickness, joints, seams, grain, pores, imperfections, wear, translucency, subsurface scattering, reflection, refraction, and edge behavior appropriate to the new material.

Structural logic: Preserve functional parts and plausible support. Adapt fasteners, hinges, bends, load-bearing areas, and contact points only as required for believable construction in the new substance.

Environmental integration: Recalculate shadows, highlights, reflected surroundings, colored bounce, moisture, dust, and nearby surface interaction. Keep the original camera, lighting direction, composition, and depth of field.

Localization: Protect every unselected person, object, surface, logo, and background detail from change.

Constraints: Do not alter the target silhouette without physical necessity. Do not let the new material spill onto nearby objects. Avoid plastic-looking surfaces, impossible thinness, floating parts, repeated texture, or changed text. Add no watermark.

Output: Return only one photorealistic final image.
```
