A comprehensive modular whitebox prototyping kit with 600+ grid-snapped prefabs, standardized 1m metrics, and pre-configured colliders for rapid level design and gameplay blockouts.DescriptionWhitebox MegaPack is a complete, modular prototyping framework built for level designers, environment artists, and gameplay programmers. Designed to eliminate friction during the grayboxing and layout phases, this kit allows you to construct playable arenas, tactical indoor compounds, and organic exterior environments in minutes.Every asset is engineered with standardized 1-meter metrics, uniform UV scaling, and bottom-corner or bottom-center snapping pivots to make Unity’s vertex snapping (V key) feel seamless.What’s Inside:13 Comprehensive Modular Categories:01 Floors & Platforms: Modular slabs ranging from 1x1m to 16x16m with varied structural thickness.02 Walls & Parapets: Full-height perimeter barriers, defensive barricades, and low-cover walls03 Walls with Openings: Standardized architectural doorways and traversal breaches.04 Ramps & Slopes: Accessible incline wedges for smooth vertical vehicle and character movement.05 Stairs: Multi-step staircases engineered with standard player step metrics.06 Pillars & Beams: Square and cylindrical support columns for overhead verticality.07 Roofs & Wedges: Angular roofing geometry, mezzanine overhangs, and angled facade trims.08 Cover Props: Half-cover and full-cover crates (0.5m to 2.0m) for sightline blocking.09 Nature & Uneven Terrain: Geometric rocks and low-poly trees for natural terrain boundaries.10 Building Blockouts: Multi-story massing volumes for rapid skyline and urban slum silhouettes.11 Fences & Railings: Concrete highway barriers, perimeter barricades, and safety edges.12 Industrial Pipes: Straight segments, conduits, and L-elbow junction pipes for overhead framing.13 Vehicle Blockouts: Scale-accurate sedan and van blockouts for believable urban scale references.Key Highlights:Standardized 1x1m Grid Material: Clean, non-distracting white checkerboard texture calibrated to real-world scale for immediate measurement.Vertex-Snap Optimized: Engineered pivots (bottom-left and bottom-center) eliminate rotation offset alignment headaches.Physics-Ready: Every prefab includes an optimized, pre-configured MeshCollider so you can drop your character controller in and start playtesting immediately.2 Complete Showcase Scenes IncludedTechnical detailsNumber of Prefabs: 600+ (Unique modular prefabs across 13 distinct categories)Number of Meshes: 600+ (.FBX format)Polygon Count Range:Minimum polygon count: 12 triangles (simple cubes, flat floor plates, barriers)Maximum polygon count: ~1,200 triangles (compound vehicle blockouts, industrial elbow pipes, spherical foliage)Average polygon count: ~80 trianglesRigging: NoAnimation: NoUV Mapping: Yes (Standardized 1m x 1m world-scale cube projection on all geometry)LODs: None (Geometry is natively low-poly and optimized for high-performance editor rendering)Types of Materials: 1 Master Grid Material (M_Whitebox_Grid)Number of Textures: 1 (T_Whitebox_Grid.png)Texture Dimensions: 512 × 512 px (Uncompressed PNG, crisp checkerboard metric)Collision: Yes (Every prefab is pre-configured with a functional MeshCollider)Render Pipeline Compatibility:Universal Render Pipeline (URP)Built-in Render PipelineHigh Definition Render Pipeline (HDRP)
