BoundingBox/BoundingSphere problem

[kabuki1974]

Hi everyone who cares to read this post!!
I have a very strange problem: I created a mesh of a tank in blender and loaded it to my app. then I calculated a BoundingBox (using Geometry.BoundingBox method) and rendered it, strangely enough the box didnt bound the mesh and was offseted about a third in t z and x directions,
Has any 1 encontered such a problem?

more strange is the fact that a diffrent mesh resulted in a proper bounding box

I think you should center the meshes pivot in blender to get a correct result with boundingbox or bounding sphere.
