Quote - Darkedge, thanks, yes that's the kind of testing I'd usually do,  good common sense stuff...

but it doesn't apply in this case because the modeling app is not a general purpose modeling app. It only generates heads, and it starts with it's own mesh, and you cannot import an object. 

I'm getting help from the app tech support, but we haven't made any progress yet, it really should not be happening. Next step: reinstall. 

Sounds then like you aren't even creating a morph at all.. you are trying to use a completely different mesh as a morph target, which simply will not work at all.

The definition of a morph is a change of point locations in an object. You aren;t changing the location of the verts in the original object atg all.. you are trying to subnstiture a completely different mesh instead.

Way too many people take way too many things way too seriously.
