Layout is handled dynamically without a floor plan reference. Camera is positioned along the path depth axis looking into the forest haze.
A wide-angle, low eye-level view of a damp, muddy forest path receding into a cold blue-gray twilight haze in the center background. Overgrown dark green bushes scrape the left and right frame edges, their wet leaves catching specular highlights from the faint low dusk light filtering through dense, towering trees.

Create a square 1024x1024 flat top-down schematic architectural floor plan diagram of a compact modern South Korean rooftop one-bedroom unit. White background, single-weight black outlines, simple geometric plan glyphs only. The layout includes an exterior rooftop landing, a small entry alcove, a compact bathroom, a central living dining area, a small kitchen nook along the north wall, and a bedroom on the east side. Fills are solid flat pastel colors with no gradients: living area in pale yellow, kitchen in pale green, bedroom in pale blue, bathroom in pale cyan, entry in pale beige, and rooftop landing in pale gray. Draw swinging doors, sliding windows as double parallel line breaks, and simple furniture shapes. Place small white circular markers with black numbers centered on key elements: 1 living area, 2 kitchen nook, 3 bedroom area, 7 front door, 8 bedroom door, 9 bathroom door, 10
Reconciled the production rooftop room floor plan with the adapter requested fp_l05_01 name. Kept key layout features and matched number circles with target narrative states.

Create a square 1024x1024 flat top-down schematic architectural floor plan diagram of an institutional animal shelter interior corridor. Clean CAD-style layout with single-weight black outlines on a white background. Show a straight central corridor path with rows of narrow wire cages running along both sides. At one end of the corridor, draw a single heavy metal door with a swing arc. Color the corridor lane flat pale gray, and the rows of wire cages in flat pale blue. Place small white circular markers with black numbers exactly once: 1 central corridor, 2 wire cages, and 3 heavy entrance door. Do not include 3D, perspective, shadows, or text inside the drawing except the numbers.
No production floor plan existed for the animal shelter. Created a custom layout with a central corridor and flanking wire cages based on director's setup summary.

Create a square 1024x1024 flat top-down schematic architectural floor plan diagram of a modern coastal villa exterior staircase. White background, single-weight black outlines, simple geometric symbols. Show a small ground-level concrete yard at the south, a narrow flight of concrete exterior stairs running upward along the building wall, and a small rectangular rooftop landing at the top. Color the stairs in flat pale gray, the landing area in pale blue-gray, and the yard in pale beige. Include a metal railing along the exposed edges and a rooftop door symbol drawn half-open on the north wall. Place small white circles with black numbers: 2 rooftop landing area, 3 exterior stair flight, 5 half-open iron rooftop door, 6 damaged door latch, and 7 foul-smell source zone. No text or 3D effects.
Adapted the production stairwell landing structure to support fp_l11_01, focusing on stairs, landing area, and the half-open door to match target camera views.
