brutalist building 3d model

Create a game-ready modular asset pack inspired by Brutalist architecture, designed for use in a modern game engine (Unreal Engine 5 / Unity HDRP). The style should emphasize raw concrete, monolithic forms, heavy geometry, and stark, utilitarian aesthetics. Core Requirements: Fully modular building system with clean grid snapping (1m / 50cm increments) Optimized for real-time performance (low-poly with high-quality normal maps) Consistent texel density across all assets Pivot points placed logically for easy assembly Proper LODs (LOD0–LOD3) for each asset Game-ready collision meshes (simple + complex) Asset Breakdown: Include a wide variety of modular pieces: Wall segments (flat, recessed, windowed, damaged variants) Corners (inner, outer, angled) Floors and ceilings (tiles, slabs, industrial panels) Roof pieces (flat roofs, overhangs, drainage structures) Staircases (straight, spiral, industrial) Pillars and support beams (chunky concrete forms) Doors and window frames (minimalist,
