An HMX Grenade with a Post-Apocalyptic Sci-fi style for the Enigmatic Forest Swamp game environment in Unity.
“The blue light only turns on when the internal sensor detects an imminent biological presence. The room is completely empty, but the light just came on.”
This is a game-ready high-explosive weapon built for high-fidelity survival, near-future thrillers, and sci-fi horror projects. It features a fully integrated emissive light graph designed to cast dynamic glow effects in dark environments.
THE WORKFLOW: ERGONOMIC RESEARCH & HARD-SURFACE PIPELINE
I didn’t just throw automatic grunge materials or generic generators at this model.
Tactile Grip Study: To anchor the asset in reality, I physically mapped the ergonomics using real-world physical objects to study exactly where the palm exerts pressure, where the fingertips compress the tactical casing, and how the index finger loops through the safety ring.
Military Photo Reference: This personal anatomical study was strictly cross-referenced with high-resolution documentary photography of operators holding and deploying real-world tactical grenades in active combat environments.
Anatomical Weathering: Micro-surface wear, sweat-grease friction zones, and roughness smudge layers were painted entirely based on this dual reference setup. Every fingerprint smudger, surface oil accumulation, and grip deformation follows genuine human usage logic, avoiding generic procedural noise.
Industrial Coating Realism: Paint-chip distribution, metallic micro-scratches, and dust deposits were carefully hand-painted to mimic the specific aging process of heavy tactical equipment and anodized military-grade finishes.
TECH SPECS & OPTIMIZATION
Tris: 8466
Polys: 4251
UV Sets: 1 (Single coordinate space layout for maximum performance).
Topology: Hand-optimized, ultra-clean game-ready topology with localized density on silhouette curves. Fully calibrated for clean deformation and seamless LOD downscaling pipelines.
Isolated Sub-meshes: Built with 100% animable separate parts (Body, Lever, and Ring are isolated sub-meshes with independent, physically accurate pivot points).
Resolution & Texel Density: Textures are authored up to 4K and delivered at an optimized 2048 x 2048 (2K) resolution. Calculated strictly based on 1:1 real-world metrics to guarantee perfect texel density without ruining your engine’s VRAM budget.
Orientation & Scale: Y-Axis UP. Native transform matrix calibrated to absolute 1:1 real-world scale (1 Unit = 1 Meter).
Real-World Dimensions: 13.5 x 6.7 x 6.7 cm | ~5.3" x 2.6" x 2.6" (Height x Width x Depth).
TEXTURE VARIANTS - STORYTELLING
This package features a calibrated dual-texture pipeline, giving you two completely separate PBR looks to show progressive visual storytelling or environmental degradation inside your game levels:
Base Wear (Tactical Operations): Highly detailed, battle-tested industrial metal showing realistic micro-scratch distribution, tactical weathering, and factory warning decals. Features sutil, hand-painted human grease and sweat friction zones around the grip area].
Deep Decay (Post-Apocalyptic): The raw, uncompromised horror version. The anodized military coating is heavily degraded, layered with dense environment grime, tactical mud, and dark, dried blood spatter across the casing.
