soviet apartment 3d model

Create a realistic game-ready 3D model of an exact Soviet/Russian Khrushchyovka apartment building based on reference images. 5-story rectangular residential block, long horizontal proportions, flat roof with slight overhang. Light beige/yellow silicate brick facade, green painted concrete base around ground floor. Soviet metal entrance canopies. Mixed resident-modified balconies: white PVC glazing, old brown wooden frames, green painted metal panels, weathered mismatched enclosed balconies. White PVC windows, some ground floor windows with metal bars. Realistic aging: dirt streaks, facade wear, uneven brick tones, old post-Soviet urban look. Include simple sidewalk, small yard strip, sparse leafless trees, low green Soviet metal fence. Technical: optimized topology for Unity, clean UVs, game-ready mesh, PBR textures, separate materials for brick, balconies, windows, metal, concrete. Photorealistic, architectural accuracy, no stylization.
