You ' re welcome . By the way , Go Blue ! Because 2003 FiestaBowl StillBitter IHateSweaterVests <| sep |> Beetles or maggots . <| sep |> IDK MAN BUT IT WORKS . What else can we call it ? ?<| sep |> Asking a direct question on the forums ? Surprised you didn ' t get banned . <| sep |> I now see what you ' re saying . I just tested ingame and I get the same effect however I did manage to get a perfectly smooth inversion over the length of an entire build area shown here which used 11 . 25 increments per track piece . Here ' s the strange finding the smooth banking tool actually made it worse . To summarise , you basically need to get the angles exactly correct in order to have smooth transitions , otherwise even the slightest variance will cause that judder effect .
