< note I haven't dug into the code either > The standard way of doing this is to time limit the loader Thread. Eg loading trees only a few per frame as time allows. perhaps into a temporary data object. The OSG LOD loader thread is an example of how to do this Cheers Norman ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
