Audio Anim Notify Tool [C++ Code Plugin] - UE5.5 & 5.4

---

NOTE: 4.27 version is no longer supported in the Epic Marketplace. Please contact me if you would like that version.

This plugin automates the time-consuming process of manually adding audio animation notifies to animations, in bulk or on a per-animation basis. It handles the automatic generation of movement notifies in the animation editor, and works in 5.4-5.5.

The aim of the tool is to, within a single interface, quickly give you synchronised sounds that are mostly suitable across a number of skeletons, animations and ground surfaces, reducing the manual work down to the fine tuning rather than the entire setup of every notify. 

The plugin procedurally generates footsteps and hand/arm movement notifies based on user-modifiable parameters. This can be done on a per-animation basis, or for all animations linked to a skeleton at once. Footsteps are detected by monitoring the proximity of the bones to the ground, and footstep strength is measured through motion velocity. Dynamic ground detection can be used as an alternative to manually setting the ground height threshold.

Hand / arm movements are detected through a weighting algorithm that takes into account velocity and positional distance comparisons to a defined reference bone (e.g. pelvis). The likelihood of an upper body limb generating a sound when it moves is linked to both the proximity to the center of the body (as it is likely to make audible contact with other surfaces), as well as the velocity of that movement. The user can define the weighting of these factors in deriving a notify event. The hand section can also be used with melee weapons and combat.

There are custom Unreal and FMOD notify classes included in this plugin that can handle surface physical material detection (through line tracing), movement strength, footstep angle (upward / downward slope) and more, providing a lot of potential for highly adaptive sound.
