Matching a top-down (plan) view in fSpy can be tricky. If you simply import a floor plan, you essentially have two scenarios:
How to handle it:
There are two ways to get this into 3ds Max:
Option A: The Native "fSpy Importer" (Recommended for Max 2024+) Newer versions of 3ds Max have started integrating camera matching tools, but the most reliable method remains the community-standard.
Option B: The Standard Workflow (Legacy)
Since we have no vertical lines (Z), we only define X and Y.
Top-Down Tip: If your photo is perfectly orthogonal (no perspective, pure isometric), the vanishing points will be at infinity—fSpy will show arrows instead of dots. That is fine.
