Impact CFX is a powerful and flexible material-based collision effects system for producing audio, particle, and decal effects from physics collisions and raycasts.
COLLISION EFFECTS
• Play audio when physics objects collide with each other, with sounds based on the collision velocity and the objects’ materials.
• Play sliding and rolling sounds.
• Emit particles on collision.
• Leave decals behind on collision.
• Support for terrains.
• Works great with rigidbodies connected by joints and ragdolls.
FOOTSTEPS
• Utilize Impact CFX to play different footstep sounds based on the material a character is walking over.
WEAPON IMPACTS
• Use Impact CFX to play sounds, emit particles, and place decals for bullet impacts.
Note that knowledge of C# scripting is required to implement footstep and weapon impact effects done via raycasting.
PERFORMANT & CONFIGURABLE
• Impact CFX utilizes Unity’s Jobs system and Burst compiler to efficiently process effects with minimal performance impact, even with hundreds of colliding objects.
• Extensive configurability means that you can optimize Impact CFX for your specific needs.
