When you try to export to a POD file using PVRGeoPOD if you hit export and the model get's all jumbled up it is because the transformation center isn't the same for all parts of the object.
First select all objects delete your history
Select object in your viewport. Edit Menu>delete by type> History
Then freeze transformations on all selected objects
Modify menu>freeze transformations.
If you get an error message like this: "Freeze Transform was not applied because subdivCylinder1.translateX has incoming connection"
