Is it possible to get the collision event from VFX Graph with regular colliders? Because I want to use GPU particles as projectiles. I think it is possible with the custom shader (GPU Instantiation mod from this page Unity - Manual: Particle System GPU Instancing) + Shuriken Particle System, but I’m not sure if this working in URP.
No, VFX Graph particles cannot interact with the Game World. What’s why it is on the GPU. You can setup a fixed collision type in a VFX graph which will be simulated but this is not interactive only useful for purely visual things. (Like water collide against a cube one meter upwards from the spawning point.)
