Common mistakes when sculpting camera 3D models include ignoring real-world proportions, overcomplicating minor details, and neglecting material accuracy—all of which reduce realism and usability.
1. **Proportion errors**: Mismatched lens-to-body ratios or incorrect button/dial sizes, often from skipping reference photos. 2. **Overdetailing**: Adding unnecessary screws, tiny logos, or irrelevant textures that slow workflow and clutter the model. 3. **Material inaccuracy**: Poorly rendering metal (too flat or overly shiny) or glass (missing lens glare/refraction), which breaks immersion.
To avoid these, use real camera references for proportions, focus on core materials (plastic, metal, glass) first, and add small details only when needed—this balances accuracy and efficiency.
