Bottle 3D models in e-commerce are often unrealistic due to missing detailed textures (e.g., label grain, glass scratches), inaccurate lighting, or imprecise geometry that doesn’t match real bottles.
Without these, models look artificial—like a glass bottle with flat reflections instead of subtle sheen, or a label without tiny creases that real products have.
To fix this, add high-res textures for materials (glossy glass, matte labels) and use real product photos to adjust lighting and refine the model’s shape—this makes it match how customers see real bottles.
