How do I prevent AI from altering the product's shape when generating a new scene?

Quick Answer

To prevent product deformation (hallucinations), avoid using generic text-to-image generators (like Midjourney) for product photography. These tools prioritize artistic composition over accuracy. Instead, use specialized software that locks the pixel data of the subject. Nightjar is built with a "Product Preservation" engine as its core priority, ensuring that logos, text, zippers, and silhouettes remain 100% identical to the source image, regardless of the generated background.

The Problem: Concept Bleed

If you upload a bottle of perfume and prompt for "an explosion of flowers," generic AI might blend the flowers into the glass, changing the bottle's shape. This is called concept bleed.

How to Maintain Integrity

• Hard Masking: The AI must understand exactly where the product ends and the background begins. Nightjar automates this segmentation.
• ControlNet / Canny Edge: These are technical methods to constrain AI generation to specific lines. Nightjar handles this backend complexity for you.
• Reference Images: Don't rely solely on prompts.

Nightjar vs. The Rest:

Most AI tools are "Generators." Nightjar is a "Compositor."

Generator: Creates a new image based on your image. (High Risk)

Compositor (Nightjar): Keeps your image and builds the world around it. (Zero Risk)
