Ah, this "bug" or whatever it is has been bothering me for years since Vue 5 upto the latest Vue Infinite 8.5. I do a search now and then on Google on the subject to see if any workaround has surfaced and found this thread today.

Interesting read, especially the finding on how Vue actually calculates it's own center point.

The biggest bother with this for me is that I usually have a workflow (in any 3D application) where I block out the scene with boxes or rough models how I want the composition and then start replacing the stand ins with detailed models as I work through the scene.

Making a few boxes, spheres, tubes, rough objects in an external app (I use modo or LightWave), and bring them into Vue for placement in the scene is fine, but as soon as I start working on the models to detail them and Vue updates them when it sees that the object file has changed they start pop around in the scene as the center point moves with each reload of the mesh. Haha, so annoying and frustrating that the pivot point can't stay in place, even between updates of the same mesh.

Anyway, it seems that the problem is at the moment unsolvable. Though, I was thinking, how are the Python possibilites regarding this? I haven't checked into the Python documentation for Vue more than briefly some time ago, but can one manipulate pivot points, how meshes imports etc from scripting? Then one might maybe be able to put together a script to deal with this?

Cheers,
