Cosmetics 3D models often look unrealistic because material properties (gloss, transparency, texture), lighting, or fine details (labels, product consistency) aren’t accurately simulated.
Cosmetics use complex materials—like reflective glass bottles, creamy lipstick sheen, or matte packaging with subtle pigments—that require precise texturing and rendering to feel real; oversimplifying these makes the model inauthentic.
To improve realism, use reference photos for accurate lighting (e.g., studio or shelf setups) and test 3D tool material presets to match real-world appearances.
