Reference Render = master scene (defaults to canvas if empty). Replacement Geometry = white / clay / SketchUp / Rhino / Revit massing. Keeps scene, lighting & materials — swaps only the building.

Import many views of the SAME building (drag & drop, files, folder, or an image URL — download Google Drive / Dropbox / OneDrive shares locally first). Analyse classifies every view, scores quality, weights them, and builds a persistent Building Memory that automatically grounds every render.
