What are the common mistakes when reduce buildings 3D models?

Common mistakes when reducing building 3D models include over-simplifying key structural/architectural details, neglecting texture resolution/consistency, and mismanaging LOD (Level of Detail) hierarchy. Over-simplifying can erase unique features (e.g., windows, cornices) that define the building’s identity, losing its character. Neglecting textures leads to pixelation or mismatched scales, breaking realism. Poor LOD causes either slow performance (from unneeded complexity) or unrealistic low-detail views. If new to reduction, start by marking critical features to preserve, test textures at your target size, and use LOD tools in software like Blender to align detail with your use case (e.g., gaming vs. architectural visualization).
