hello,
I saw, there is a difference with activating symetry-option in SP, when dealing with fbx or obj.
For obj, "Z" axis is offest form the center (see images below), the same model as fbx does have it centered (!)
Both models got the same base (everything centered, frozen and "zeroed out", also tri-angulated in 3D app, MODO 10 indie)
just saved in different format.
Why is there a difference in axis-geometry???
