求助，osgearth添加了星空背景和光照，在加入模型之后出现地球变黑问题
osgearth添加了星空背景和光照，在加入模型之后，视角移动到某些位置会出现地球消失的问题代码如下，求大佬指点
#include "stdafx.h"
int main()
{
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer;
osg::ref_ptr<osg::Group> root = new osg::Group;
osg::ref_ptr<osg::Node> earthNode = osgDB::readNodeFile("gdal_tiff.earth");
osg::ref_ptr<osgEarth::MapNode> mapNode = osgEarth::MapNode::findMapNode(earthNode);
osg::ref_ptr<osgEarth::Util::EarthManipulator> em = new osgEarth::Util::EarthManipulator;
em->getSettings()->setArcViewpointTransitions(true);
viewer->setCameraManipulator(em);
//root->addChild(mapNode); //同时加载mapNode和m_pSkyNode会出现瓦片闪烁
if(mapNode.valid()) em->setNode(mapNode);
//设置星空，添加光照
{
osgEarth::Config skyConf;
double hours = skyConf.value("hours", 6.0);
osgEarth::DateTime dateTime(2020, 8, 29, hours);
osgEarth::Util::Ephemeris* ephemeris = new osgEarth::Util::Ephemeris;
osgEarth::Util::SkyNode* m_pSkyNode = osgEarth::Util::SkyNode::create(mapNode);
m_pSkyNode->setName("SkyNode");
m_pSkyNode->setEphemeris(ephemeris);
m_pSkyNode->setDateTime(dateTime);
m_pSkyNode->attach(viewer, 1);
m_pSkyNode->setLighting(true);
m_pSkyNode->addChild(mapNode);
root->addChild(m_pSkyNode);
}
//添加一个模型
{
const osgEarth::SpatialReference* geoSRS = mapNode->getMapSRS()->getGeographicSRS();
osg::Node* model = osgDB::readNodeFile("cow.osg");
model->getOrCreateStateSet()->setMode(GL_RESCALE_NORMAL, osg::StateAttribute::ON);

geoSRS->getEllipsoid()->computeLocalToWorldTransformFromLatLongHeight(
osg::DegreesToRadians(40.0),
osg::DegreesToRadians(116.0),
100000.0, Lmatrix);
Lmatrix.preMult(osg::Matrix::scale(osg::Vec3(10000, 10000, 10000)));
osg::MatrixTransform* mt = new osg::MatrixTransform;
mt->setMatrix(Lmatrix);
mt->addChild(model);
root->addChild(mt);
}
viewer->setSceneData(root.get());
viewer->run();
return 0;
