I know how to export a modified OBJ as a Morph Target and then load it back into the original prop as a dial. However, the shape distorts in odd ways in between the zero and 1 positions. It only looks right at zero or 1, not in between. So I can't do a gradual, partial morph, it has to be all or none.

 So I would like to combine several in-between morphs that I have exported as OBJ files. How can I put them all together so that bends of 30, 45, 60, 75, and 90 degrees (for example) can just be different positions on a single dial instead of 5 different dials?

Even better would be a way to prevent the 90-degree bend, for example, from distorting in between zero and 1. But I don't know if that is possible.
