I am working on a small project that involves importing an stl file of misaligned teeth into blender, segmenting them and realigning them. For accuracy, I need to import an image of a curve into the blender background over a set of misaligned teeth then aligning them accurately along the curve. So far I have managed to segment the teeth, realign and animate them, but having a challenge using shape keys to get the gums to move accordingly with the teeth.The surrounding tissue, the gums, should be deformed to adapt to the new form of the jaw and tooth position. Also, how do I make the stl file look realistic with colors like the final animation?
This is the blender file with the animated teeth: https://wetransfer.com/downloads/baedee1c92b41c6f4dc7e6196ecb268220190602182550/00afb1
