In Autodesk Maya,the default coordinate system is Y-up.
In Epic's UDK,the default coordinate system is Z-up.

If I set the up-axis in Maya to the Z-axis in the Maya preferences window,then will it be "exactly" the same as in the Unreal Development Kit ?
Or will there always be some kind of difference,even if both (Maya and UDK) have Z-up ?

Thanks.
