Trekkie, yes, diversity is good.

But do we really need completely different figures for that ?

Gramps and little Maggie above are the exact same mesh. Do they look "samey" to you ?

Using the new morphbrush, it would be no technical problem to transfer your Simon/Snape face over to David3WM for example.

Then you could have the face you want AND you could use D3WM's better rigging.

If you use Simon, you'd either have to live with his rigging or weightmap him yourself.

And if you use yet another figure, same problem. A new set of problems that needs to be fixed.

But if all figures are derived from a single mesh, support gets much easier.

 

Anyway, nice Snape morph.  :-)

(He could really need some potion to fix his shoulders, though) ;-)

 

Use what you want and you're happy with.

My point is:

There is only so much time and energy. I think I achieved more diversity by focussing on a single mesh than by trying to make a lot of different meshes work for me.
