# TECH ART OUTSOURCE - Vertex Animation

![](Documentation~/Images/ProjectCastle_01.gif)

A vertex animation baking tool, shaders, and animation system for Unity DOTS/ECS.  

Render tens of thousands of models at the same time each with its own animation state.  

## Features

- Vertex animation model baker

  - Multiple animations (stored in one Texture2DArray)

  - LOD generation

  - Prefab generation

  - Animation book generation

- DOTS animation system

  - Simple API

  - Animation library and books

- Shaders

  - Lit vertex animation shader

  - Interpolation

  - Normal encoding and decoding

  - Shader graph support

### Model Baker

Artist friendly GUI for converting models.

### DOTS Animation System

Sample code to play an animation.

```C#

protected override void OnUpdate()

{

    float deltaTime = UnityEngine.Time.deltaTime;

    Entities.ForEach((Entity entity, ref VA_AnimatorComponent ac) =>

    {

        // Get the animation lib data.

        ref VA_AnimationLibraryData animationsRef = ref ac.animationLibrary.Value;

        // Set the animation index on the AnimatorComponent to play this animation.

        ac.animationIndex = VA_AnimationLibraryUtils.GetAnimation(ref animationsRef, animationName);

        // 'Play' the actual animation.

        ac.animationTime += deltaTime * animationsRef.animations[ac.animationIndex].frameTime;

    }).ScheduleParallel();

}

```

### Shaders

Lit example shader (build in shader graph).  

Full shader graph support.

## Install

[Installing from a Git URL](https://docs.unity3d.com/Manual/upm-ui-giturl.html)

[Documentation](Documentation~/VertexAnimation.md)

## Getting Started

- Example 1: Mainly used for testing.

- Example 2: Contains an animation system that shows how you could setup animated characters and a spawning system to test performance.

- Example 3: MonoBehaviour example for if you are not using DOTS.

## Extra Info

This project is developed by the TAO (Tech Art Outsource) group at BUAS (Breda University of Applied Sciences).

There are plenty of improvements to be made, e.g.:

- (Optional) per bone vertex animation (instead of per-vertex), this can reduce the texture size needed to store the animations.

- Add option to export rotation map separately instead of compressing into the alpha channel, this will make it slower but higher quality.

- The LOD generation is very basic and slow, the ability to swap out algorithms would be cool.

- Split different modules into separate packages (LOD generation, animation baker + shaders, and the animation system)?

- Multi-material and/or sub-meshes support.
