So sorry I haven’t replied yet @1sgjoshking . I received a message privately from the crew, after they checked out my model etc. It turns out, at the moment, the wobble is unavoidable for this model, and it is not the fault of a tracking image.
This solution, however, doesn’t fit with the plan. I wanted to make something as tangible as possible, where they could rotate and manipulate the virtual object as if it existed via the physical tracking image. Oh well. it isn’t fun unless you hit the limits
