Common mistakes when styling environment 3D models usually involve overcrowding scenes, ignoring scale consistency, and neglecting lighting harmony.
Overcrowding clutters spaces and hides the intended design; scale issues (e.g., tiny furniture next to oversized decor) break realism; mismatched lighting (cool LEDs in a warm bedroom) disrupts immersion.
To avoid these, start with a clear theme (e.g., "rustic kitchen"), add elements gradually, and use reference objects (like a standard table) to check scale while testing lighting for mood consistency.
