Image to 3D for Blender: what to check after AI generation

AI image-to-3D tools are useful, but I would not treat the generated model as finished the moment it exports.

For Blender workflows, I usually think of image-to-3D as a fast starting point, not a replacement for checking the mesh.

My basic workflow is:

1. Start with a clear source image.
2. Generate a first 3D model from the image.
3. Rotate the model before exporting.
4. Export OBJ or GLB if I want to keep editing.
5. Import the model into Blender.
6. Check the mesh, material, scale, back side, and floating fragments.
7. Export the final format only after cleanup.

The file format matters here.

STL is useful for 3D printing, but it does not preserve material information. If I plan to keep working in Blender, OBJ or GLB is usually a better intermediate format.

The common problems I look for are:

• too many faces for the intended use
• broken or strange back-side geometry
• floating fragments
• missing or distorted materials
• wrong real-world scale
• front-facing detail that does not hold up from the side

That is why I prefer a workflow where the AI model is generated first, then inspected and cleaned in Blender.
