no find Stars

[luohuiiqng]

After adding the sky, only the sun and moon are observed, no stars are seen.

ref_ptr ViewerWidget::addSky()
{
osgEarth::DateTime dateTime(2023, 12, 5, 20);
ref_ptr sky_node = SkyNode::create();
osgEarth::Util::SkyOptions skyOptions;
osgEarth::Util::Ephemeris* ephemeris = new osgEarth::Util::Ephemeris;
sky_node->setMoonVisible(true);
sky_node->setName("sky");
sky_node->setDateTime(dateTime);
sky_node->setLighting(true);
sky_node->attach(m_viewer, 0);
sky_node->setSunVisible(true);
sky_node->setStarsVisible(true);
sky_node->setEphemeris(ephemeris);
bool re = sky_node->getStarsVisible();

return sky_node;

}
