Model Baker

Artist friendly GUI for converting models.

DOTS Animation System

Sample code to play an animation.

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.
