QUESTION FFB mesh conversion smoothing

[Trawa]

So I got my track all nice and dandy BUT
no matter whether my FFB mesh (cloned visual layer) consists of 700k polys (tesselate + subdivide) or 7k polys (original) it's bumpy as hell. Whats even funnier - another part of the track is perfectly smooth with just 7k of polys. I ran out of ideas. Smooth, TurboSmooth, MeshSmooth, quadify - nothing. No matter what I do the bumps stay there.

This is how visual mesh looks like.
Tesselated + subdivided

IT'S STILL BUMPY AS HELL.

Quadified + subdivided

Same result. These anomalies might be causing bumps though.

Mesh link if anyone wants to take a look.

Any and all help will be greatly appreciated.

Maybe its an "anti-rip" feature Turn 10 inserted into their Bernese Alps mesh...

You are not alone Trawa.
I too would be very grateful for a non esoteric method to do this, as I have not had alot more success than you have had using trial and error.

Well, if this is indeed a rip (and I tend to trust John), then people will be less keen to jump and help you around here..
