VFX Physics is an advanced particle physics simulation tool designed specifically for Unity's Visual Effect Graph. It adds realistic environment collisions and inter-particle interactions that run entirely on the GPU, enabling you to create complex physical behaviors without sacrificing performance.
What makes VFX Physics unique:
- Built from the ground up for Unity 6000.0+ and VFX Graph
- No coding required — configure everything through familiar VFX parameters
- Automatic buffer management with dynamic capacity scaling
- Spatial hashing grid optimization for fast neighbor searches
- Supports Box, Sphere, Capsule, Mesh (with custom BVH), and Plane colliders
- Swept collision detection prevents tunneling on fast-moving particles
Perfect for:
- Sparks, embers, and fire debris
- Rain, snow, and hail
- Swarms, flocks, and crowd simulation
- Fluid-like particle behaviors
- Explosions and destruction effects
- Industrial simulations (conveyor belts, hoppers, sorting)
What's included:
- BoPhysicsSpawner component for VFX Graph integration
- BO_WorldColliders_Block subgraph for environment collisions
- VFX_BO_ApplyParticleInteractions block for particle-to-particle physics
- Complete sample scene with example effects
- Multi-language documentation (EN, RU, JA, KO, ZH-CN)
All parameters are exposed as VFX properties, making it easy to connect to your existing VFX graphs. Debug tools help you visualize collider detection, grid distribution, and particle behavior directly in the Scene view.
