I am currently using the osgShadow NodeKist. It only works when I use osgViewer as default graphics context. Now the case is, I have to assign a third party graphics context to the main camera as we are using a Qt Gui for buttons etc. After I assign osgViewer::GraphicsWindowEmbedded to the main camera, the scene cannot be drawn. Only clear color is displayed. So I assume that since the graphics context has been changed, do i have to specify where the shadow texture need to be binded?
