fSpy defaults to generic units. Always try to find a known dimension in your photo (like a standard counter height of 90cm) and adjust your fSpy grid guide accordingly before importing.

fSpy assumes a "perfect" lens. If your photo was shot with a wide-angle lens, it likely has "barrel distortion" (curved lines). For top-tier results, undistort the image in Photoshop or Lightroom before bringing it into fSpy. Conclusion
While Blender has an official fSpy importer, 3ds Max users utilize a script (available via GitHub or ScriptSpot) to automate the import.
Ultimately, the "top" workflow is the one that gets you from a single photo to a perfectly matched 3D scene in the least amount of time, freeing you to focus on the art of creation rather than the chore of calculation. : Requires the standalone fSpy app to be
Once your camera is placed in 3ds Max via one of the methods above, you need to match your viewport settings to ensure the overlay aligns seamlessly.
Enable the 3D guide box. Adjust the grid scale to match a known real-world dimension in your photo, such as a door height or wall length.

Master 3D Camera Matching: The Ultimate Guide to fSpy and 3ds Max
In the world of 3D design, the bridge between a flat photograph and a three-dimensional world has long been a hurdle for artists. For years, matching a virtual camera to the exact perspective of a real-world image required tedious trial and error—until the emergence of fSpy. Originally a standalone open-source tool, fSpy has become the "secret sauce" for many artists working in Autodesk 3ds Max, transforming how they approach architectural visualization and environment design.
