To fix missing textures in FBX 3D models, confirm texture files are in their original relative folder (e.g., a "Textures" subfolder next to the FBX), then re-link them using your 3D software’s texture management tool (like Blender’s "Find Missing Files" or Unity’s "Fix Now"). FBX stores texture file paths (not the textures themselves), so moving or renaming files breaks these links—reconnecting restores the model’s appearance. If re-linking doesn’t work, try re-exporting the FBX with "embed textures" enabled (if your software supports it) to bundle textures directly into the model. For future use, keep textures in a consistent subfolder alongside the FBX to avoid this issue.
