Face Character into -Y for Max; +Z for Maya.
To make life smoother, all rigs in 3ds Max should be facing in the -Y direction, which is also the default for any Biped created; +Z for Maya. This helps with consistency for the production and it also plays nicer with the scripts that have been written for the exporter.
