Hi Fausto, Dynamically modifying the scene graph shouldn't be that hard. Removing drawables and adding news ones should perfect safe and shouldn't require and extra steps from you, no need to dirty bounding volumes or display lists, it should all just work.
As to why your new drawables aren't appearing I can't say. Try writing the subgraph they are in out to a file then load this file into osgviewer to see if can view them. It could be simply that there is something wrong with the geometry data you've set up. Only you has your app and your data so you're the only one that can investigate. Robert.
