UnityでVRMを動かす方法

参考：https://konichallengelog.com/unity_vrm_lipsync/

人形素材をDLとインストール

  1. https://3d.nicovideo.jp/works/td32797 からDL
  2. DLしたdirを、UnityのAssets以下にドラッグ
  3. VRM内の青色アイコンのPrefabを、ヒエラルキーにドラッグして、表示されればOK

UniVRMのインストール

Package/manifest.jsonのdependencies以下に、com.vrmc〜の4行追加 

  "dependencies": {
    "com.vrmc.vrmshaders": "https://github.com/vrm-c/UniVRM.git?path=/Assets/VRMShaders#v0.107.0",
    "com.vrmc.gltf": "https://github.com/vrm-c/UniVRM.git?path=/Assets/UniGLTF#v0.107.0",
    "com.vrmc.univrm": "https://github.com/vrm-c/UniVRM.git?path=/Assets/VRM#v0.107.0",
    "com.vrmc.vrm": "https://github.com/vrm-c/UniVRM.git?path=/Assets/VRM10#v0.107.0",

Unityプロジェクトを開いて、Packagesの下に、VRMが、あれば成功。

モデルを動的に読み込む場合

pathは適当。読み込み時間は7秒ぐらいかかる。 

using UnityEngine;
using UniGLTF;
using VRM;
using VRMShaders;

public class SampleScene : MonoBehaviour
{
    async void Start()
    {
        string path = Application.streamingAssetsPath + "/../Alicia_VRM/Alicia/VRM/AliciaSolid.vrm";
        Debug.Log(path);
        RuntimeGltfInstance instance = await VrmUtility.LoadAsync(path, new RuntimeOnlyAwaitCaller());
        instance.ShowMeshes();
    }
}

笑顔に変更 

using UnityEngine;
using UniGLTF;
using VRM;
using VRMShaders;
VRMBlendShapeProxy proxy = vrmObj.GetComponent<VRMBlendShapeProxy>();
proxy.SetValues(new Dictionary<BlendShapeKey, float>
{
    {BlendShapeKey.CreateFromPreset(BlendShapePreset.Joy), 1.0f},
});
