[]laya2.0版本支持MeshColliderShape吗

2.0测试版的MeshColliderShape是可以用吗，我这样添加之后报错
let sp3d = scene.getChildByName("GameObject").getChildByName("dimian_5");
let rigidBody = sp3d.addComponent(Laya.Rigidbody3D)
let shape = new Laya.MeshColliderShape()
shape.mesh = sp3d.meshFilter.sharedMesh;
rigidBody.colliderShape = shape;

如果把报错的地方注释掉，下面这行报错 btGImpactMeshShape找不到
this._nativeShape=new physics3D.btGImpactMeshShape(triangleMesh)
 
全局搜了一下这个btGImpactMeshShape都没找到
