Hi Daniele, The best to implement multi-thread updates of the scene graph is to prepare your new scene graphs in the separate thread then merge these with the main scene graph during the update phase, this way you avoid modifying anything that is being currently traversed. This is how the DatabasePager manages multi-threading loading and expiry of subgraphs.
In svn/trunk and 2.9.11 there is also an new osganalsyis example that has a simple example of custom paging in a background thread that adds and removes subgraphs from the main scene graph in the main viewer thread.
