Common mistakes when styling car 3D models include ignoring real-world proportions, overcomplicating details too early, and neglecting material consistency.
Ignoring proportions (like unrealistic panel gaps or tire-to-body ratios) breaks realism—even small mismatches stand out. Overcomplicating details (e.g., trim, decals) before finalizing core shapes (hood, body lines) slows workflow and complicates big changes. Neglecting material consistency—such as a glossy finish on a normally matte bumper—makes the model look unpolished.
Start with basic shape blocking, use real car photos to verify proportions, and test material swatches (paint vs. plastic) early to keep finishes cohesive.
