-    Generate structured 3D meshes from a 2D image using the PartCrafter pipeline.
-
-    This function takes a single 2D image as input and produces a set of part-based 3D meshes,
-    using compositional latent diffusion with attention to structure and part separation.
-    Optionally removes the background using a pretrained background removal model (RMBG),
-    and outputs a merged object mesh.
-
-    Args:
-        image_path (str): Path to the input image file on disk.
-        num_parts (int, optional): Number of distinct parts to decompose the object into. Defaults to 1.
-        seed (int, optional): Random seed for reproducibility. Defaults to 0.
-        num_tokens (int, optional): Number of tokens used during latent encoding. Higher values yield finer detail. Defaults to 1024.
-        num_inference_steps (int, optional): Number of diffusion inference steps. More steps improve quality but increase runtime. Defaults to 50.
-        guidance_scale (float, optional): Classifier-free guidance scale. Higher values emphasize adherence to conditioning. Defaults to 7.0.
-        use_flash_decoder (bool, optional): Whether to use FlashAttention in the decoder for performance. Defaults to False.
-        rmbg (bool, optional): Whether to apply background removal before processing. Defaults to True.
-        session_id (str, optional): Optional session ID to manage export paths. If not provided, a random UUID is generated.
-        progress (gr.Progress, optional): Gradio progress object for visual feedback. Automatically handled by Gradio.
-
-    Returns:
-        Tuple[str, str, str, str]: 
-            - `merged_path` (str): File path to the merged full object mesh (`object.glb`).
-
-    Notes:
-        - This function utilizes HuggingFace pretrained weights for both part generation and background removal.
-        - The final output includes merged model parts to visualize object structure.
-        - Generation time depends on the number of parts and inference parameters.
