Hi,
thanks Carsten. THat's because I do not delete viewport 0, which displays
the scene;
See line 220, remove the comment, then the render node will show nothing
==========================
line220:
beginEditCP(MDWndPtr);
//MDWndPtr->subPort(ptrViewport); // if we delete the viewport 0, the
render node will display nothing
for(int i = 0; i < g_ndivx*g_ndivy; i++)
{
cout<<i<<endl;
MDWndPtr->addPort(g_pptrViewport[i]); // I add new viewport to work
with camera decorator, but it fails to work
}
endEditCP(MDWndPtr);
===========================
