Is this postwork or is there some way to do this?
I'm stuck at work, so haven't yet had a chance to play with it.
In the promo images, there's one awesome pic with half of M4's face and the other half the M4 Cyborg.
Well the promo blurb says you can conform the cyborg to M4 so I'm guessing that that was what was done, to treat it as a skeleton and then a custom transparency MAP was generated to make parts of M4 invisible.
No doubt ofiicial word will materialise but that's what it looks like to me.
It's that pic that realy sold this for me
