An extremely detailed, highly constrained image generation prompt for Nano Banana Pro to create a hyper-realistic 3D isometric cityscape entirely constructed from textile art, specifically embroidery and weaving. The prompt strictly prohibits non-textile materials (stone, metal, wood) and enforces rules for visible thread ends, hand-made authenticity, and Japanese text labels for historical and geographical elements. The user must input the name of the city to be depicted.

Ultra-realistic 3D Isometric Cityscape Embroidery - Complete Textile Art ＾＾＾＾＾＾＾＾＾＾＾＾＾＾＾＾＾＾ A textile masterpiece depicting the historical memory, cultural layers, architectural evolution, and current identity of **{argument name="city name" default="[Enter City Name]"}**, where all architectural structures are entirely constructed using embroidery and weaving techniques. The entire scene exists on a base of linen or raw canvas fabric. 🚫 Absolute Material Rules (Important) ❌ Forbidden Materials: Stone, concrete, metal, glass, wood, plastic ✅ Allowed Materials: Embroidery thread, bundles of thread, fabric folds, textile padding, layered stitching, knots, seams, weaving textures only Core Concept - Architecture as Textile Sculpture Architecture is interpreted as sculptural embroidery. Volume is created by: Extreme relief embroidery (high-relief stumpwork) Vertically stacking thick bundles of thread Multiple overlapping stitch directions Soft padded fabric cores completely wrapped in thread ⚠️ Structure must appear physically sewn, not modeled. Thread Density and Hand-Made Imperfection - Mandatory All architectural forms must have densely layered thread and heavy-looking seams. ✅ Structures should look: Over-embroidered Carefully crafted stitch by stitch Slightly imperfect Hand-made Edges and Thread Behavior - Mandatory All buildings, monuments, and woven structures must include the following elements: ✅ Mandatory Elements: Visible frayed thread ends Frayed embroidery edges Microscopic thread fibers extending from seams Slightly undone stitch tips at corners Edge Characteristics: Soft, sewn, fiber-based feel Organic, sewn contours with hanging threads Tactile edges ❌ Forbidden: Sharp edges Perfect contours Clean 3D shapes ⚠️ Important: Buildings must never give a rigid impression. All corners are: Separated by stitching Softened by overlapping thread Slightly rounded by fabric tension Thread knots, stitch junctions, and small thread ends are visible Handmade Authenticity Rule The entire scene must feel: Handmade Tactile Created in a textile atelier ✅ Acceptable Features: Slight variations in stitch tension Differences in thread thickness Subtle unevenness in placement ❌ Forbidden: Perfect symmetry Embroidery Content Section (Mandatory) 1. City Identity and Geographical Location City name in thread embroidery Geographical location via stitched map contours Strategic importance as a stitched annotation Trade routes via thread flow Embroidered compass and edge annotations 2. Iconic Buildings and Construction Dates Name, construction year, civilization, function Flat contour stitching with adjacent embroidered date tags Layered, 3D embroidered architectural forms completely constructed with thread 3. Historical Layers and Ancient Civilizations Example: Ancient, Medieval, Early Modern, Modern Delicate sketch embroidery Semi-relief remnants Layered textile forms 4. Major Events and Important Dates - Chronology Founding, wars, disasters, reconstruction, modernization, etc. Timeline embroidered with thread Stitch direction arrows Major dates in red thread 5. Current City - Complete 3D Embroidery Only Bridges, towers, silhouettes Modern architecture Visual Continuity Rule - Absolute ✅ Mandatory: All thread flow must seamlessly connect structures, dates, symbols, and the modern cityscape. ⚠️ Important: The city must appear as a single, continuous piece of embroidered fabric. Lighting and Technical Specifications Lighting: Soft atelier lighting Side light highlighting raised embroidery Realistic textile shadows Technical Specifications: 8K resolution Cinematic depth of field Unreal Engine 5 rendering Museum-quality textile realism Ultra-detailed thread texture Text Language Rule - Mandatory All text elements displayed in the generated image must be written in Japanese. Target Text: City name Historical periods and civilizations Building names and construction dates Cultural annotations and symbolic meanings Map annotations and geographical descriptions Chronology events and stitched labels Museum-style annotations and sketch annotations ❌ Forbidden: English, foreign languages, or mixed-language text ✅ Mandatory: Only correct, legible, and context-appropriate Japanese embroidered text Visibility Rule for Textile Base - Absolute (Important) The embroidery must be unmistakably stitched onto a visible fabric surface. Mandatory features of the underlying fabric: Linen, raw cotton, or coarse canvas Visible fabric weave (warp and weft clearly identifiable) Natural fabric slubs, fiber irregularities, and fabric tension Slight fabric wrinkles, folds, and creases caused by stitching 🚫 Forbidden: Floating embroidery Digital relief Sculpted objects ✅ Mandatory: All stitches, structures, and thread masses are visibly fixed to the fabric surface Pulled through and penetrating the fabric surface Mandatory Fabric Interaction Details The fabric surface slightly warps due to stitch tension Pulling the thread creates subtle depressions and raised areas Needle entry and exit points are implied by stitch behavior The fabric texture remains visible between dense embroidery areas Excess Thread and Thread End Rule - Absolute (Important) All three-dimensional embroidered elements must show visible thread excess and unfinished thread behavior. Mandatory for all 3D objects (buildings, monuments, bridges, towers, terrain, symbols, relief text elements): ✅ Mandatory Features: Loose thread ends protruding from the surface Excess thread ends coming out of stitch junctions Small loops and overlaps of thread that are not fully tightened Slightly tangled or overlapping clumps of thread at corners and stress points Occasional hanging thread tips casting soft textile shadows 🚫 Forbidden: Neatly finished embroidery Hidden or perfectly trimmed thread ends Machine-perfect finished stitches Smooth, sealed, or sculpted surfaces Enforcement of Craft Authenticity Thread ends must look: Handmade In progress The work of a craftsman finishing a textile piece ✅ Acceptable Features: Thread ends with slightly uneven length, direction, or tension Rendering Keywords Ultra-high density embroidery, overstitched textile structures, visible loose threads, frayed stitch ends, hand-sewn 3D textile structures, tactile fiber realism, stitched volume (not shape), thread-composed shapes Note: This guideline is a strict standard for creating museum-quality artwork composed entirely of textiles. All rules are absolute, with no exceptions.
