usesharedvertices

it is possible within a single mesh: a submesh with
usesharedvertices = "true" and another with usesharedvertices = "false"?
That is, there may be sharedgeometry and geometry in the same
mesh?
I have tried in every way that I happened
but always gives me the error when rendering.
Use the ogreXmlConverter.
forgiveness for the drafting, but I am using the translator
of google.

Not really Aall the vertices are merged together and duplicates removed; it's just how it is.

I have a character with morphanimation for the face
and skeletalanimation for body.And mayaexporter
does not allow export the two types of animation at a time.
vertexanimation want to use only the submesh face,
but for that I have to put usesharedvertices = "false".
And if you do not use sharedgeometry in the rest of submeshes,
the file up too much space.
if anyone knows any other way of joining Vertex and Skeletal animations ask him to tell me.

Back up a little. We are talking about PhysX Triangle or Convex meshes here right?
