Creating Blend Shapes In Maya

[persius]

Hello.

I'm new to animating in Maya 8 and recently begun some attempts at creating blend shapes. I have been refering to the Digital Tutors training DVD on creating blend shapes. They use a model which is actually made up of SubD's. My project must be done in Poly's, so I'm a little uncertain as to why SubD's would be used when Polys are the norm from my understanding?

To put it simply, what type of mesh should I be working with when using polys? that is, a low density, or high? Also, is there a way to create a blend shape in SubD and then convert it to Poly? Basically, I would like to make life as easy as I can for myself.
If there are experienced animators who can offer suggestions on how to do this, I would really appreciate hearing back from you.

Thank you.

D.

Theres nothing norm about polys over subdiv. Blend shapes work exactly the same over both of them

quite simply where you want the blend to happen in history. Theres plenty of reasons to put it at both places can't know ahead of time since i dont kneo your history chain or intent.

Only way to know is to undertand how things work. Even then its a question fo what your after.

There are no rules to do things in the world, the only thing that lats you decide each optimum is to understand how you do things.
