Input
Prompt
Create a highly optimized, lightweight 3D asset of a stone arch with natural vegetation overgrowth, designed specifically for real-time rendering and web usage. The arch is made of large, weathered stone blocks with visible age and erosion. Climbing ivy and plants grow organically around the arch, following gravity and stone cracks. VEGETATION DETAILS (CRITICAL): - Leaves must be SMALL, dense, and fine-grained - Leaf scale should be noticeably smaller than the stone blocks - No large or oversized leaves - Use tightly packed foliage cards to create visual richness without heavy geometry - Avoid chunky or sparse vegetation STAIRCASE DESIGN (CRITICAL): - Add a LARGE stone staircase directly under the arch opening - The staircase must fill most of the arch height - Steps should be wide, tall, and monumental - Staircase scale should feel dominant and architectural - The staircase must visually align with the arch curvature and proportions - Low geometry, no bevel-heavy steps CRITICAL OPTIMIZATION RULES (DO NOT IGNORE): - Total triangle count: max 25,000 (ideal 15–20k) - No sculpted micro-detail geometry - All small surface details must be baked into normal maps - Vegetation must use alpha planes (cards), NOT individual leaf meshes - Stone blocks should reuse geometry via modular repetition - Use texture tiling and trim sheets where possible - One UV set only - Minimal draw calls (shared materials) GEOMETRY PRIORITIES: - Focus on clean silhouette and strong shape readability - Medium poly for main arch silhouette - Very low poly for stairs despite large scale - Planar geometry for foliage - No hidden or internal geometry TEXTURES & MATERIALS: - PBR workflow - Max texture resolution: 2K - Stone material: tiling texture with baked AO and subtle moss variation - Ivy material: alpha transparency, fine leaf masks, subtle color variation - Use packed texture maps where possible (ORM) STYLE & VISUAL DIRECTION: - Realistic stylized (not photogrammetry) - Natural but intentional composition - Calm, neutral lighting - Ancient ruin, timeless feel TECHNICAL OUTPUT REQUIREMENTS: - Clean quad-based topology - No ngons - Correct real-world scale (monumental staircase proportions) - Pivot at ground center - Asset centered at world origin - Export-ready for Blender, Three.js, Unreal Engine, WebGL BACKGROUND: - Transparent or white background
