Realistic 3D Apparel Mockup generator with Chatgpt prompt

Generate a highly realistic 3D product photography rendering of an apparel item uploded, specifically a t-shirt, presented as a professional mockup.

Subject & Composition:
A single t-shirt, completely isolated and centered within the frame, appearing to float or be suspended without visible support. It must be presented in a clean, straight-on front view, ensuring the entire shirt is fully visible and occupies the central focus.

Apparel Details:
* Type: Short-sleeve t-shirt.
* Fit: Designed to convey a loose, relaxed, free, comfortable, and casual aesthetic.
* Sleeves: Should drape naturally, appearing loose and relaxed.
* Fabric: High-quality, soft cotton jersey texture. Emphasize realistic fabric characteristics like subtle weave, natural folds, and gentle wrinkles that enhance its soft, worn-in feel.
* Color: {SHIRT_COLOR}
* Design Area: The front surface of the shirt must be smooth and taut enough to clearly display a graphic design. If a design is to be included, it will be overlaid here. (For a blank mockup, omit specific design details).

Rendering Style & Realism:
* Quality: Photo-realistic, high-definition 3D rendering.
* Details: Include meticulous stitching details, collar seams, and hem finishes characteristic of quality apparel.
* Shadows & Lighting: Implement soft, diffused studio lighting that minimizes harsh shadows on the shirt itself, while adding subtle, natural cast shadows beneath the suspended shirt to enhance its 3D depth and realism against the background.

Background:
Clean, minimalistic studio background (e.g., pure white, light grey, or a subtle gradient) that allows the t-shirt to stand out without distraction.

Output Goal: A high-resolution image suitable for digital product presentation, e-commerce, or design prototyping, focusing on the shirt's material integrity, form, and overall casual appeal.
