Yeah cool, I already found it but thanks. I read the whole thread.
Looks like I might be able to "hack" it into what I want it to do, but essentially, having played PJ Racers you will know how it would be difficult to implement the lane changing using the path plugin.
It would be awesome if it supported path tweeing and/or multiple paths for a single object.
As it stands I may be better off making some kind of custom node system which in turn puts me off the project. I was looking for something I could make quickly with little to no headache. I just feel like pumping something out over the course of a week, not a few months or years (like Tonks >.>)
