I want to generate a car model, but the result is very poor – the surface looks patchy and low-resolution. `python train_full_pipeline.py -s data3 -r "dn_consistency" --high_poly True --export_obj True` How can I make this result better? <img width="907" height="692" alt="Image" src="https://github.com/user-attachments/assets/bd3d9790-aec6-40cb-82b7-48c37896161f" />
