Spline editor for Unity 3D which will bend a model?

I’m looking into creating levels dynamically, what I’d like to do is have a really long corridor type thing with many segmented parts then use a spline to bend the model along those segments and develop the appropriate collision mesh to match it (3D studio max has this built in but obviously it won’t allow for dynamic level creation).

Is there a plugin which can do this for me? I tried searching on the store but there were a few and I’m not sure if any do or don’t support what I want…

I think MegaFiers is something to do this.
