IGameMesh::InitializeData crashes when exporting mesh

[e_juma]

It happens when exporting objects in the scene. Do I miss any preparing operations before exporting?

My codes is very simple:

    pIgame->InitialiseIGame(node);
    int count = pIgame->GetTopLevelNodeCount();
    for (int loop = 0; loop < count; loop++)
    {
        IGameNode* child = pIgame->GetTopLevelNode(loop);
        auto name = child->GetName();
        IGameObject* obj = child->GetIGameObject();
        switch (obj->GetIGameType())
        {
            case IGameObject::IGAME_MESH:
            {
                IGameMesh* gm = (IGameMesh*)obj;
                if (gm->InitializeData())

The user set the length and width of the plane with a very huge value on UI. And in script window, I can check the value is nan.0.
