Hi Manu, Extending the .osg format with your own callbacks/nodes/state/drawables is pretty easy - just look to see how all the NodeKits do it i.e. they have src/osgPlugins/osgParticle, src/osgPlugins/osgText.
The .ive format isn't extensible in the same way though, to extend it you have to go in a add support directly for you data type. The is a flaw with the .ive format, and makes it inappropriate for the type of work you have in mind. Longer term I'd like a native osg binary format that is extensible, but alas its quite a chunk of work so not possible to introduce any time soon. Robert.
