I've posted tutorials on how to create morphs in Blender in the past.

Here's the core gist.

Work from the unimesh figure model obj in geometries.

When you import it uncheck split by obj

Check polygroups

Check keep vertex order.

Sculpt

Export

Check only 

Polygroups

Vertex order

Apply as full body morph by the Figure Menu load full body morph.

That's it.

You can zoom on the figure by pressing the period or dot key. Dont scale the figure. It's not necessary in Blender. I've created hundreds upon hundreds of morphs in Blender without scaling, the dot zoom works fine for even the finest details. Anyone that says otherwise is WRONG.

If you want to change the camera focal press the N key and change the focal in the view tab. Press N again to dismiss. Do not subdivide or tesselate. Simply use the sculpt tools on the base resolution.
