Haptic Volumes allows a user to feel haptics through a collider set to Haptic Trigger shared on the same slot.
Haptic Volumes can be paired with Haptic Filters placed on the same slot to give more precise control over a user's haptics. Each haptic filter is applied by multiplying each influence together, hence being multiplicative.
This works as part of the game's robust Haptics system.
The type of haptic you want to do, for controllers the haptic types are subtly different variations. Specifying this is useful for haptic suits that have more advanced haptic motors.
