Sequence Options

The sequence options sub-panel is used to set the animation export mode.  Most models should use the single pass animation mode.  The two pass animation mode can be used as a workaround for problems with models that have non-uniform (anisotropic) scale animations.  Because the two pass animation mode has the potential to cause data loss in Blender's scene data, it should only be used as a last resort.  See notes on anisotropic scale for more information.
