To improve AI-generated 3D models for promotional videos by enhancing texture generation with higher-resolution diffusion models, procedural texturing, UV mapping refinement, and GAN-based texture synthesis.
Here is the code snippet you can refer to:

In the above code we are using the following key points:
- Stable Diffusion XL for High-Resolution Textures: Generates photorealistic textures.
- Text-Prompt-Based Texture Control: Allows fine-tuned details via descriptive prompts.
- Automatic Texture Saving & Display: Ensures easy integration into 3D models.
- Device-Agnostic Execution: Runs on GPU (if available) for efficiency.
- Supports Custom Texture Types: Can generate a variety of material textures (wood, metal, fabric, etc.).
Hence, improving AI-generated 3D models for promotional videos requires advanced texture synthesis using diffusion models, detailed UV mapping, and GAN-based procedural enhancements to achieve lifelike, high-resolution details.
