Summary

Hi,

When I xref a hairstyle and change the distribution surface, everything is working ok. When it's time to render with vray I have to place a vrayornatrixmod as it seems it is not propagated properly through the xref (it is on top of the stack of the hair style in the xreffed file). Next time I open the scene the hair style is no longer attached to the distribution surface. Also, I noticed that when you have vrayornatrixmod on top of the xreffed hairstyle, the oxoverridedistributionsurface function fails to update the distribution surface (it sets the user property just fine but it is ignored somehow).
