[osg-users] converting .osg to .obj

Hello, Is there a way to convert an .osg file to an .obj file, a .3ds file, or something similar. I am unable to open .osg files in 3ds max or Maya and hope to find some kind of plugin to convert the data. Thank you, Scott -- Read this topic online here:

Re: [osg-users] converting .osg to .obj

Hi Scott, The fastest way is to use osgconv application, which automatically loads osgdb_obj plugin for writing: # osgconv filename.osg filename.obj It seems the osgdb_3ds plugin does not support writing at present. But this will soon be solved by Sukender's submission, I think. :D 2009/11/25
