Here is a third version of this effect (made following Andrew Kramer's tutorial at http://www.videocopilot.net/tutorials/

Like I said at FE.org I do this shots to learn after effects more than to add even MORE CGI to Indy 4. But ID is interested by the concept of "teleportation" for his edit. So I'm toying with after effect and 3DSmax to see what can be done.
The goal is to make all skeletons vanished kind of like Spalko later. And the alien is "teleported in" by a reverse version of this effect (starting by the head). So when Spalko vanished we can assume that they are "teleporting" her more than just killing her.
I don't know if I can make shots realistic enough to be used in this edit, but I'm trying!
But I think ID could end with 2 versions of his edit, a "purist" and a more "let's our imagination rolls" version. So don't be afraid, we don't want to add CGI just for the pleasure to add CGI! ;)
Bonus: a new look for the alien
