Animation Sharing Plugin

Choose your operating system:

Windows

macOS

Linux

The Animation Sharing Plugin provides a way to create shared animation systems that reduce the overall amount of animation work needed for a crowd of Actors. Based on the Master Pose Component system, Animation Sharing utilizes a set of animation state buckets for which animation instances are evaluated. The resulting poses are then transferred to all child components that are part of the bucket.

The diagram below provides a high-level breakdown of how the system works:

  1. Individual Crowd Actors (AActor)

  2. UAnimationStateProcessor instance that is part of the Animation Sharing Setup

  3. Runtime manager that is initialized using the Animation Sharing Setup

  4. States (enum named), which the user has set up

  5. Runtime representation of the state that takes the form of a Skeletal Mesh Component

  6. Master Pose Component system used to share the animation with the child Skeletal Mesh Components

In the example video below, a Blueprint with a Skeletal Mesh Component cycles through several Animation States. A group of individual Actors is also shown where the Animation State of each Actor is determined based on the Animation State of the Skeletal Mesh Component in the Blueprint.

Enabling the Animation Sharing Plugin

In order to use Animation Sharing, you will need to enable the Animation Sharing Plugin from the Edit > Plugins menu under the Programming section:

You will need to restart the Editor after enabling the plugin.

Animation Sharing Setup Asset

The Animation Sharing Setup asset contains all the information that will be shared across the specified Actors. You can create an Animation Sharing Setup asset inside the Content Browser under the Animation category.

AnimSharingSetup.png

Inside the Animation Sharing Setup asset, you can define the following properties:

NewAnimSharingAsset.png

Skeleton Setups

The ability to add multiple Skeletons along with their corresponding settings is available by clicking the + (plus sign). This is useful when you have multiple Skeletons and Skeletal Meshes that will be driven by animations during animation sharing.

Property

Description

Skeleton

The Skeleton asset to be replicated.

The Animation Sharing Setup is specific to the specified Skeleton.

Skeletal Mesh

The Skeletal Mesh to be replicated.

This is used for debugging poses only.

Animation Blueprint for Blending

The Animation Blueprint that is a child of AnimSharingTransitionInstance .

You must create and set up one of these to handle blending between states. Additionally, every time a blend is required, one of these is generated and ran to handle the transition which adds a cost.

Animation Blueprint for Additive Animation

The Animation Blueprint that is a child of AnimSharingAdditiveInstance used for additive animations.

Inside your Animation Sharing Setup asset, you will also need to set Animation State to On Demand and enable the Additive option.

State Processor Class

Interface class used when determining which state an Actor is in.

This needs to be set in order to add the Animation States.

Animation States

This is an array that holds all the states the Actor can be in. Each state is its own bucket.

Animation States

AnimationStateSection.png

Once you define a State Processor Class inside your Skeleton Setup , based on the states within it, you will be able to define the following properties for each of your Animation States .

Property

Description

State

Define which state you want that index of the array to contain information for.

This is inherited from the State Processor Class and the assigned Animation State Enum.

Animation Setups

This enables you to define the per state Animation information such as which Animation Sequence to play, what Animation Blueprint to use for playing back the Anim Sequence, number of randomized instances (if desired), and whether or not the setup is enabled for specific platforms.

On Demand

Whether or not this state is classified as on-demand, which means you can kick off a unique animation when needed. This spins up a unique instance per on-demand animation.

When reaching the maximum value, it will snap to the nearest animation.

Additive

Whether or not the state is an additive state.

On-demand must be enabled and you will need an Additive Animation Blueprint to handle blending.

Blend Time

Duration of blending when blending to the state.

Maximum Number Of Concurrent Instances

The number of instances that will be created for the state (platform-specific).

Requires Curves

Whether or not this animation requires curves or morph targets to function correctly for slave components.

Scalability Settings

ScalabilitySettingsSection.png

The following properties are available under the Scalability Settings section:

Property

Description

Use Blend Transitions

If the animation should play a blend to transition from one state to another.

Blend Significance Value

Significance value tied to whether or not a transition should be blended.

Maximum Number Concurrent Blends

The number of blends that can be running at the same time.

Each animation that is over this limit will snap to the nearest one.

Tick Significance Value

Used with the Significance Manager. Anything over the specified value will not be ticked.

Animation Sharing State Processor

The AnimationSharingStateProcessor class is a specialized Blueprint class (or you can use the native C++ class) that is used to determine what state you are currently in. To create this class of Blueprint, create a new Blueprint of the AnimationSharingStateProcessor class and enter a desired name for the Blueprint.

The Animation Sharing State Processor Blueprint should only be used for prototyping. Runtime performance will be greatly improved by using the native implementation as opposed to the Blueprint implementation.

AnimSharingStateProcessorClass.png

In your Blueprint, in the Details panel, set the Animation State Enum to an enumeration containing your Animation States.

ProcessorDefaults.png

The Animation Sharing State Processor Blueprint is also the Blueprint Class that you will define as the State Processor Class inside your Animation Sharing Setup asset (pictured below). After defining the State Processor Class, you can add Animation States by clicking the + (plus sign) to represent each state in your enumeration.

AnimationStatesDefined.png

The Animation Sharing State Processor Blueprint can override two functions. The first, the Process Actor State function (pictured below), can be used to find out what Actor you are editing the state for. The second overridable function, Get Animation State Enum , should be used to return the Enum class from a native Animation Sharing State Processor and can be used for interacting with the native implementation.

ProcessActorStateExample.png

Click image for full view.

In the image above, we override the Process Actor State function and cast to a Blueprint called Husk_BP to retrieve its Animation State (stored in a variable we have created). The Animation Sharing State Processor Blueprint is also assigned inside your Animation Sharing Setup as the State Processor Class .

Animation Blueprint Setup

You will need to set up an Animation Blueprint to handle the blending between the Animation States. This requires a special class of Animation Blueprint called an Anim Sharing Transition Instance . Create an Animation Blueprint from the Content Browser , then in the Pick Parent Class menu, select your desired Skeleton asset and the AnimSharingTransitionInstance as the class.

AnimBPCreation.png

On the AnimGraph of the AnimSharingTransitionInstance Animation Blueprint, copy or use the setup depicted below.

Anim Sharing Additive Instance

When using additive animation, you will need to use an Animation Blueprint of the AnimSharingAdditiveInstance class.

AnimSharingAdditiveBP.png

Animation State will need to be marked as On Demand and Additive enabled inside your Animation Sharing Setup asset.

Anim Sharing State Instance

This Animation Blueprint (AnimBP) class enables the ability to add AnimBP behavior if the user would like to do so as it exposes two properties by default: Animation to Play and Permutation Time Offset . On a basic level, this is what should drive the pose.

As for the native implementation, it exposes GetInstancedActors which returns all AActor(s) that are currently being driven by this state. That way , in case there are Notifies, they can be handled correctly and propagated to the unique instances.

This is achieved by overriding HandleNotify and handling it accordingly.

Animation Sharing Manager

In order for Animation Sharing to be executed at runtime, you will need to create an Animation Sharing Manager that points to your Animation Sharing Setup asset. This can be called through Blueprint inside any Actor (or from the Level Blueprint) with the Create Animation Sharing Manager function.

CreateAnimationSharingManager.png

You can also call the following functions targeting an Animation Sharing Manager:

Function

Description

Animation Sharing Enabled

Returns whether or not Animation Sharing is enabled.

Get Animation Sharing Manager

Returns the Animation Sharing Manager (or null if none has been set up).

Register Actor

Registers an Actor with the Animation Sharing Manager, according to the specified Sharing Skeleton .

In the image below, we use Get Animation Sharing Manager and Register Actor to register our Husk Actor with the Animation Sharing Manager (we also enable input in the Blueprint so that we may change the Animation State with a key press).
