I hadn't noticed that, but you're right.  The choice is gone.

 

Here's a quickie script that brings back the choice (turns anti-alias OFF):

import poser
scene=poser.Scene()
scene.SetRenderAntiAliased(0)

For a script that restores the Anti-alias, change the 0 in the last line to 1 and resave under a different name.

I tried it in P9; not convinced it's actually doing anything, but it doesn't give an error. 

Your aliasage may vary.
