Thanks guys, worked perfectly with a little test setup I did. Maze - Yeah I've heard good things about Nuke, but I've got a license of AE so may as well use it!
thats comp, you might give a try to nuke, really robust for this kind of work. just like they said render your passes and combine them in a comp software. The lines and stuff thats up to you. I ll suggest you do something of your own really. I ll probably do all that in illustrator, bring it to photoshop for subtle…
