ParallelSplitShadowMap问题求助

//标识阴影接收对象
const int ReceivesShadowTraversalMask = 0x1;
//标识阴影投影对象
const int CastsShadowTraversalMask = 0x2;       
mls = new osg:: LightSource();
       
        mls->getLight()->setPosition(osg::Vec4(0,1,-0.5,0));
        osg::Vec3 lightDir(0,1,-0.5);
        lightDir.normalize();
        mls->getLight()->setDirection(lightDir);
        mls->getLight()->setAmbient(osg::Vec4(0.2,0.2,0.2,1.0));
        mls->getLight()->setDiffuse(osg::Vec4(0.8,0.8,0.8,1.0));
        mRoot->addChild(mls);

        //创建一个阴影节点，并标识接收对象和投影对象
        mShadowedScene = new osgShadow::ShadowedScene();
        mShadowedScene->setReceivesShadowTraversalMask(ReceivesShadowTraversalMask);
        mShadowedScene->setCastsShadowTraversalMask(CastsShadowTraversalMask);

        //pssm阴影初始化
        osg::ref_ptr<osgShadow:: ParallelSplitShadowMap> psst = new osgShadow:: ParallelSplitShadowMap(0,3);
        psst->setTextureResolution(1024);
        psst->setPolygonOffset(osg::Vec2f(1.0,1.0));
        mShadowedScene->setShadowTechnique(psst);

    mShadowedScene->addChild(mls);  
        mShadowedScene->addChild(mRoot);//和上行顺序调整也不对
       
       
    m_Root->addChild(mShadowedScene.get());//m_Root是场景根节点
  
   模型都添加在mRoot下
出现如下画面：
问题在哪儿呀？

咋没有人回答我问题

阿威

看不出啥问题

是不是顺序不对啊？
