Animated GLB Models

Play animations from streamed GLB/XRG models using the SDK's hybrid animation system.

How It Works

The SDK bridges a Legacy Animation component (drives the mesh) with an Animator component (runs your state machine). This is necessary because clips are loaded dynamically at runtime and cannot be embedded in an Animator Controller asset at edit time.

Morph target (blend shape) animations play automatically as part of clip playback — no extra setup needed.

Inspector Setup

1. Enable Log Animations on StreamingModel to see available clip names at runtime.

2. Create an Animator Controller asset with states. Assign a dummy AnimationClip to each state, named to match the model's clip name (e.g. "Idle", "Walk").

3. Assign the controller to Custom Animator Controller on StreamingModel.

4. Press Play.

Clip matching: The SDK matches by exact name first, then by numeric index (e.g. "0", "1").

Animation Modes

Mode	Behavior
Auto	Default. Uses EmbeddedClips without a controller; VrmMecanim if controller + humanoid bones.
EmbeddedClips	Standard path for animated GLBs.
VrmMecanim	Mecanim humanoid retargeting. Requires humanoid skeleton.
None	No animation.

Quick Code Reference

// Wait for load, then control animations
streamingModel.SetLoadedCallback(() =>
{
    streamingModel.PlayAnimation("Idle");
    streamingModel.SetAnimationFloat("Speed", 1.0f);
    streamingModel.SetAnimationTrigger("Jump");
});

// Swap controller at runtime
streamingModel.RuntimeAnimatorController = newController;
