I need clean, black-and-white 3D models of an upper and a lower dental arch built natively in Blender. Each jaw should rotate, pan and zoom freely without clipping or distortion, so the scene hierarchy and pivot points must be set up with that in mind. Please add orthodontic attachments to selected teeth. These attachments have to remain fully parametric: I want to reposition, resize or hide them at any moment, and the underlying tooth geometry must stay intact when I do so. A simple on/off control (collection toggle or driver) for every individual attachment is enough, as long as it is clearly labeled inside the .blend. If you can give me a well-organized .blend file, I will be happy. I’m open to an extra export in .obj or .fbx after everything is approved, but Blender is the working file I need. Acceptance criteria • Separate, watertight meshes for upper and lower jaws, pure black-and-white material setup • Global controls that let me orbit, pan and zoom the full model smoothly • Non-destructive attachments: editable, movable and individually toggleable • Clean, named scene hierarchy and no unapplied transforms Turnaround is flexible but I’d like to see a first draft to spin around by the middle of next week.
