Pro Physics Engine: Production ready physics toolkit with destruction, advanced cloth, water, wind & soft-body simulation. Custom kernel delivers 3x faster performance than Default standard physicsThis Package Use: Burst, MathematicsBring Virtual Physics to Life with Uncompromising RealismPro Physics Engine is a comprehensive physics simulation system for Unity that fuses high-performance computation with creator-friendly workflows. Developed by Inbora Studio, this asset enables developers to create worlds that bend, tear, flow, and break exactly as they should live, in-game, and under complete control.What Makes Pro Physics Engine Stand OutCustom Physics Kernel ArchitectureAll physics modules run on a dedicated custom InboraPPX kernel (224-bit) that provides tighter control over simulation behavior, deterministic options for repeatable results, and significantly improved scaling across multiple CPU cores. This architecture ensures consistent physics across Mac, Linux, Windows, and consoles 100% unified platform simulation.Water & Fluid PhysicsCreate dynamic water simulations with realistic object interactions influenced by scene geometry. The fluid solver simulates natural water movement, currents, ripples, and splashes responding to interactions. Supports both 2D and 3D fluid modes including marching cubes for surface meshing, particle-based fluids, raymarched volumetric rendering, and screen space fluid passes. Optimized to maintain excellent performance even with complex water simulations handling 100k+ particles at just 1.2ms per frame.Wind Physics SystemSimulate wind forces acting on cloth, foliage, and soft bodies with customizable wind profiles ranging from gentle breezes to strong gusts. The node-based system allows fine-tuned control over how wind affects different materials and surfaces, with integrated collision tuning ensuring realistic responses.Advanced Cloth SimulationFeatures responsive, wind-woven cloth profiles using a node-based system for natural behavior. Collision tuning is built-in for ready-to-use cloth interactions without extra setup. Includes specialized presets: collision-aware cloth, smooth damped cloth, dynamic high-motion cloth, interactive cloth with mouse/rig grabbing, wind-reactive cloth, and tearable cloth with customizable thresholds for dynamic fabric destruction.Soft-Body Dynamics DuoCoreFlex System: Optimized for jelly-like soft body deformations with plasticity for realistic squish/stretch effectsFiber Morph Technology: Simulates anisotropic, thread-like distortions realistically for rope-like and organic soft bodiesDestruction & Slicing 2.0Combines hybrid pre-fractured models with runtime fracture capability. Features faster plane and knife cuts with stable multi-slice performance, ensuring watertight results with no gaps or holes. Automatically generates inside-surface UVs and materials for seamless texturing. Enhanced debris pooling reduces overhead during destruction events while preserving mass and center of gravity dynamically for authentic physics behavior.
