They function as static environment obstacles that physics projectiles and debris can bounce off of, keeping runtime physics calculations highly efficient.Zero Draw-Call Material Tinting: Visual randomization is driven by an optimized workflow. The shader variation script executes its assignment logic exclusively during Edit Mode. It leverages Unity 6's native Renderer.SetShaderUserValue API to inject packed data directly into the instantiation pipeline. By keeping this calculation out of runtime execution, it eliminates Play Mode frame-rate spikes during mass firing and destruction events, ensuring 100% compatibility with the GPU Resident Drawer and SRP Batcher with zero material cloning.Memory & Data Packing (VCCore Architecture)Minimal VRAM Footprint: The primary workflow leverages an atlas-free, highly optimized vertex color and index system. Foundational PBR data and surface detail IDs (e.g., wood vs. metal) are baked directly into the mesh vertex data, routing procedural surface details dynamically via the shader to drastically lower texture memory overhead.UV3 (V Channel): Detail Index baking for high-fidelity procedural surface detail (wood grain, hammered iron, etc.).Advanced UV Channel Mapping: Discrete data arrays are mapped directly to individual hardware channels to preserve rendering performance:UV1: Metallic / Smoothness (MR) maps.UV2: Fully preserved and dedicated for clean, production-ready Lightmap baking.UV3 (U Channel): Ambient Occlusion (AO).RSUV Randomization: Implements Per-Instance Randomization (RSUV) that dynamically carries over across mesh transitions and fractured LOD states on destroyed parts.Universal Pipeline Compatibility & Legacy Fallback: Formatted for URP out of the box and fully compatible with HDRP. For developers who prefer a traditional texture-based workflow, a fallback texture set is included. Standard 4K PBR source files for the siege weapons are downscaled to 2048x2048 by default in Unity to balance fidelity and memory, while the accessory textures are 2K natively.Physics & Code ArchitectureStable Shatter Hierarchies: Every pre-fractured component and ammunition prefab is rigorously structured with accurate local axes to ensure stable, jitter-free physics simulations upon impact or collapse.Event-Driven Combat Loop: The framework features a comprehensive event-driven architecture. The custom inspector exposes native Unity Events for breaking, loading, reloading, and firing states, allowing developers to seamlessly link external gameplay logic, UI systems, or custom audio/VFX triggers without modifying the core codebase.Clean Namespaces: All codebase architecture is strictly encapsulated within custom namespaces (DPT.SiegeWeapons and DPT.SiegeWeapons.Editor) to guarantee zero naming conflicts with existing project scripts.Compilation Pipeline Footprint: Code compilation is modularized across isolated, platform-restricted Assembly Definitions (.asmdef). This decouples package scripts from the global project compilation pass, shortening iteration times and providing absolute build security by automatically stripping editor dependencies from final application builds.Asset Specifications & Geometric DensityThis framework features a semi-modular construction. Polycounts are broken down into base stationary variants, allowing you to deploy them as static defensive emplacements or combine them with the included axle and wheel sets for mobile field configurations.Heavy Artillery (Base Stationary Assemblies): 2,900 to 5,100 triangles at LOD0. Aggressive LOD chains reduce these down to under 600 triangles at a distance.Modular Mobility Components: Wheels and axles range from 100 to 580 triangles at LOD0, scaling down to just 32 triangles for distant rendering.Battlefield Cover & Ammunition Props: Scatter props, mantlets, and ammunition range from 30 to 670 triangles at LOD0, ensuring you can clutter your battlefields without performance hits.Particle Mesh Elements: Ultra-optimized visual meshes (4 to 48 triangles) utilized by the dynamic VFX systems to maintain high framerates during intense, physics-heavy destruction simulations.Optimization Note: Micro-assets under 20 triangles, such as high-tension ropes and alignment strings, intentionally bypass further LOD steps. Keeping these static avoids unnecessary runtime component switching overhead where vertex savings would be net-zero.Audio Framework & Technical SpecificationsMaterial-Mapped Audio Toolkit: Includes 37 uncompressed 16-bit PCM .wav source files (preventing double-compression artifacts and maintaining sample-accurate audio boundaries) pre-mapped to structural mechanics and impact profiles.Specialty Audio Actions: Tailored operational sound assets covering mechanical movement, high-tension rope creaks, burning fuses, whistling projectiles, and heavy surface-specific impacts (wood splinters, metal breaks, rock shatters).VFX System Integration: Accompanied by 8 custom particle prefabs (covering wood splinters, metal splinters, rock shards, fire, smoke, sparks, and rolling debris) that synchronize dynamically with script-driven impact execution. Also includes an impact crater, impact trench and impact cracks mesh that spawn procedurally on impact.Requirements & CompatibilityUnity Version Compatibility: Formatted, tested, and verified for Unity Engine version 6000.3.8f1+ and higher. Built in 6000.5.4f1.Included Assembly Definitions: DPT.Core (Shared Framework Core), DPT.SiegeWeapons (Package Runtime Core), DPT.SiegeWeapons.Editor (Platform-Restricted Editor Inspectors), and DPT.SiegeWeapons.Demo (Sandbox Scene Code).Input System Dependency: Interactive test scene components rely on UnityEngine.InputSystem.
