To make an FBX 3D model look clean, optimize its geometry, textures, and hierarchy while resolving common issues like overlaps or unused data.
- **Simplify geometry**: Remove unnecessary polygons, fix high-sided messy faces, or merge overlapping vertices to cut clutter. - **Clean textures**: Delete duplicate files or resize textures to match the model’s scale. - **Organize hierarchy**: Rename objects, delete empty groups, or remove unused materials for clarity.
Use built-in tools like Blender’s "Clean Up" menu or Maya’s "Reduce"/"Merge Vertices" to automate basic fixes before manual adjustments.
