[osg-users] 3D model preparation question

A few of my 3D model files (which are in .obj format) look different when 
loaded into Blender compared to viewing them in osgviewer.  I can see all 
the colors clearly in Blender but in osgviewer the model appears dark.  I 
have attached a few pictures here.  I commonly see this with older model 
files that have materials specified but no associated textures.

I am a developer and not a 3D modeler so I don't have enough Blender 
experience to know why it looks different in that software.  Is there 
something else I need to do to prepare these models for use in OSG?  I know 
that Blender places a light in the scene but I thought that osgviewer had a 
small light pointing out of the camera as well.

Any help would be appreciated.  Thanks,
