Add default nodemask
Idea should be to add a default nodemask in config and bind it in the gui.
I'm currently using Blender and osgExport and I've seen that the exporter doesn't assign any nodemask to the exported scenegraph. Setting nodemasks from blender might be useful to identify/preprocess some imported models in osg.
I'm a total noob in python, but the modified version of osgobject.py does the trick of setting a default nodemaks.
Do you think it's hard to retrieve the nodemask value from the config file, or expose a control on the exporter GUI? That would be a nice add on!
