This was my hardest experiment. The goal was to turn an AutoCAD plan and rough 3D walls into an accurate interior render. Nano Banana Pro read furniture placement from the plan, Flux 2 Pro applied the style, and Flux 2 Max corrected alignment. Kling o1 generated the video but couldn’t understand the back side of the space. The final solution was correcting Kling’s last frame with Flux 2 Max, then rerunning Kling using the first frame, corrected last frame, and motion reference, resulting in a clean, unscalable video.
