Imported meshes impact scene ( possibly the lighting? )

[jaycarson]

Blender Version 2.79
OSG Version: 3.4.0-9
Operating System: Fedora

I have been using Blender's export utility to export obj files and then using osgconv to convert them to osg files. The files are then imported and rendered into a scene that looks like:

Today I installed this converter to directly export from Blender to osgt files. I get the following results when I import those files and render them.

Additional Details:

• The code is set to follow the human character. The rest of the scene is static.
• When I use the old human model I get the working effect, but the whole purpose of using the converter is to be able to export its animations.

Any ideas? I saw the effect and I don't really even know where to start. The only difference is the outputted file from the converter. Everything else is the same. Also, if there is a newer/better way to export blender files into files that OSG can read, then I'm open to any and all suggestions.

Thank you in advance,
Jay
