At the moment MouseEvent3D does not detect whether the alt key is held. It is fixed by changing in MouseEvent3D.as (lines 166-173)
result.localZ = localZ;
result.ctrlKey = ctrlKey;
result.shiftKey = shiftKey;
return result;
}
to
result.localZ = localZ;
result.altKey = altKey;
result.ctrlKey = ctrlKey;
result.shiftKey = shiftKey;
return result;
}
