Your electronics 3D model looks unrealistic in photography mainly due to incorrect material settings (e.g., overly glossy plastic), poor lighting, or low-resolution textures lacking real-world details.
Real devices have specific light interactions—like a phone’s metal frame showing soft reflections or a remote’s plastic being slightly matte. If your materials don’t match this, authenticity is lost. Flat or harsh lighting fails to accentuate features (buttons, edges), and blurry textures miss small details (screen grains, logos) that make real electronics feel tangible.
In tools like Blender or Keyshot, use material presets for real electronics (e.g., “brushed aluminum” for laptops) and add soft directional lighting to mimic studio shots. High-res textures (1024x1024+) for screens or casings also help.
