Ahh... Sorry you are quite right having multiple roots is just like having more branches as long as the roots don't duplicate any geometry and or hierarchial state optimizations Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
