[osg-users] Cannot render and load OBJ when using QOpenGLWidget with osgViewer::GraphicsWindowEmbedded on OSG 3.5.6 rc2 and 3.6.4

[OpenSceneGraph Users]

HI,
I've tried to export the scene to osgt file and I found that it writes the 
structure of the node i.e. Geode s Geometries vertexes colors..etc. but the 
with all values set to zero. That's why they're not seen.
