Thanks for your quick reply. The same behavior happens on many different models. For instance, base.dae in https://github.com/PR2/pr2_common/tree/indigo-devel/pr2_description/meshes/base_v0.
The STL models, iin the previous link, are rendered fine. I haven't tried any other formats. I got slightly confused. I have two different integration of OSG in Qt: - The first one is the OSG examples. With DAE models, it renders an empty scene (I tried pressing the space bar), - The second version is a bit messy as it is not really a unit test. It is located here: https://github.com/jmirabel/hpp-gui/blob/devel/include/hpp/gui/osgwidget.hh and https://github.com/jmirabel/hpp-gui/blob/devel/src/osgwidget.cc. With DAE models, it renders black triangles as in the screenshot. The problem happens on version 3.2 and 3.4. On another computer which I do not have at hand now, I was able to display DAE by first converting them to the OSG format using osgconv and then viewing the converted file. But my current computer, I get the same result as in the screenshot. Thank you!
