Your photo 3D model is blurry mainly due to low-resolution source photos, insufficient angle/texture coverage, or reconstruction software limits. Low-res photos lack detail for sharp edges, while too few angles mean the software can’t map surfaces accurately. Some tools also struggle with flat or reflective textures, leading to fuzziness.
To fix this, take 20+ well-lit, clear photos from all sides of the object—this gives the software more data to build a sharper model.
