I met the same issue.
I generated some mesh model by myself and tried to convert it from obj to osgb by osg3.4.1. It can only be read by osg3.4.1 and can’t by 3.5 or 3.01.
I want to put the mesh into another software for editing, so i tried to use 3.01 where the editor uses, but the new problem is the model generated by 3.01 can't be read by 3.4.
Have you solved the problem?
Could you give more details to help?
