Actually, coming from Blender, I have found that things don't rotate properly on the x-, y-, and z-axis if I don't centre my mesh to that little centre thingie prior to exporting to objects, so... but maybe it's just a Blender thing.

When I import and obj into Poser, I untick all the boxes (particularly when importing something I'm going to conform to V4) and it pretty much lands where I exported it in Blender.

Not sure if that's what's meant by Obj centre point information...
