Why do you want to make 3D using Boris fx? I've seen your other posts (and not be rude or anything) why do you need all these plugins for your programs?
1. Sony vegas is capable to do 3D without some extra plugin
2. If you have adobe after effects (that can do 3D easily) why do you need to do 3D in sony vegas?
3. Where do you get the money to get all these plugins and both sony vegas and adobe after effects? Cause if you're downloading these illegally you could be charged or tracked down.
4. and Finally both of these programs are capable of making a great amv without having plugins for them.
But to be honest hardly any editors use Boris plugins, so I don't think you'll find a awnser any time soon.
Just play around with it and you'll get the basics soon.
