Impact Object – The Impact Object collision data will be sent to. If empty, it will attempt to find an Impact Object on the collider that was hit or one of its parents.

Impact Triggers are components that tell Impact Objects when to play interactions and with what data. They are the origin that provides the data which is sent to the object’s Impact Material to ultimately play the interactions defined on the material.

Impact Object Rigidbody uses FixedUpdate to ensure accurate interactions, especially when sliding and rolling. However, this can cause overhead if there are a lot of objects.

Any Impact Triggers must be on the root of the object (the same object as the Rigidbody), and should have their Impact Object field empty. Impact Triggers must be on the same component as the Rigidbody,

Impact Object Single Material is the simplest type of Impact Object, with a single material used for the object. It is most suited for static objects and level geometry. You can add this script to your objects by going to

Priority can be used to ensure that certain objects will always play their interactions, even if it requires "stealing" resources that are already in use.

Impact Objects are components that you attach to the objects in your game’s world to specify their material, so that other objects (and other parts of your game) know how to interact with them. Impact Objects can also provide physics data such as rigidbody velocity.

The Audio Source Template prefab must have an Impact Audio Source component attached to it.

Pool Size – The size of the object pool created for this audio source.

Impact Materials define what interactions will occur when an object interacts with the tags defined in the Impact Tag Library

The size of this buffer limits the number of interaction results that can be returned by a single interaction, so make sure this is set appropriately for how many interaction results your materials can return.

This is a hard limit that will be checked as soon as a collision message is recieved. If the limit has been reached for that fixed update frame, processing will be aborted immediately. Typically you would want to set this to be about the same size as your object pools. Triggers can be set as High Priority to ignore this limit.

Material Mapping works best for static, single material objects. Without an Impact Object component attached, no material composition or velocity data can be obtained

Material Mapping allows you to map Unity's Physics Materials to Impact Materials. This is useful so that you don't necessarily have to add an Impact Object component to all of the objects in your scene.

For example, if you have a terrain you will probably want to set this to the number of textures your terrain uses.

The first field is an Impact Tag Library which is used to display a user-friendly dropdown for the tag or tag mask. The second field represents the actual value of the tag or tag Mask

Just remember that under the hood tags are represented only by integers, so using multiple tag libraries with different tag names does not mean you can have more than 32 tags.
