I am having a problem with a prop I made. I'm getting unwanted facets showing on part of the prop.

A is the prop, it has a small sphere hidden inside it. B is the morph, the sphere has been expanded and looks smooth. C is the prop A, with the obj B applied to it as a morph target.

So why is the morphed prop displaying facets, and is there any way to fix it. I'm a bit limited for tools, just Poser and UV Mapper.

As a bit of extra background, the torus and sphere were made in UV Mapper, then imported into Poser, where the sphere was scaled down, and the two props exported as a single obj, but containing two separate groups. The same process was repeated, but with the sphere unscaled to produce the morph obj. I have since tried merging the groups in both the prop and the morph, but that does not seem to help. Any ideas?
