FBX模型在XNA 4.0中未正确显示

Question

我有一个问题，即XNA 4.0无法正确显示3D FBX模型。

一个朋友创建了一个模型，当我在FBX查看器中打开此模型时，它会正确显示它https://docs.google.com/open?id=0b54ow8grluduytbubtq4bjbramm

但是当我将其加载到XNA中并单击运行时，它显示为https://docs.google.com/open?id=0B54OW8GRLUDUSE14TWMXCNBJWWC

The code that i have for the drawing is
foreach (ModelMesh mesh in model.Meshes)
{
    foreach (BasicEffect effect in mesh.Effects)
    {
         effect.Projection = projection;
         effect.View = view;
         effect.World = Matrix.CreateScale(1.0f) * Matrix.CreateRotationX(90) * Matrix.CreateTranslation(position);
         effect.EnableDefaultLighting();
     }
     mesh.Draw();
 }

任何帮助解决此问题的帮助将不胜感激。

谢谢。

每个网格都有一个骨头...您应该使用它将网格放在正确的位置...此代码来自Microsoft

private void DrawModel(Model m)
{
    Matrix[] transforms = new Matrix[m.Bones.Count];
    float aspectRatio = graphics.GraphicsDevice.Viewport.AspectRatio;
    m.CopyAbsoluteBoneTransformsTo(transforms);
    Matrix projection =
        Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f),
        aspectRatio, 1.0f, 10000.0f);
    Matrix view = Matrix.CreateLookAt(new Vector3(0.0f, 50.0f, Zoom),
        Vector3.Zero, Vector3.Up);
    foreach (ModelMesh mesh in m.Meshes)
    {
        foreach (BasicEffect effect in mesh.Effects)
        {
            effect.EnableDefaultLighting();
            effect.View = view;
            effect.Projection = projection;
            effect.World = gameWorldRotation *
                transforms[mesh.ParentBone.Index] *
                Matrix.CreateTranslation(Position);
        }
        mesh.Draw();
    }
}
