Hi! Include element is pretty straightforward and functional. But, it would be nice to perform a reposition (and reorientation, maybe) of the included model. Something like: <include file="rover.xml" pos="10 15 0" quat="1 0 0 0" override="false"/> Where pos would be a new position, quat would be a new orientation and override would be a flag that states if both pos and quat would be added to what we have in rover.xml or if pos and quat would be overridden by this include atributes. Regards.
