    Yes.

    But in your screenshot polys are tris. Best practice is use quads instead. I don't regonize where you took that screenshot (3ds max viewport?) or what kind of settings you got in viewport, but tris should be avoided.

    You should always setup 3ds max to use metric units, as rF/rF2 is build to use them. Otherwise you might get unwanted result.

    In this case I would rebuild track surface, just to rule out some conversion hickups. Only then you can be sure if this is track mesh related problem. You can use old mesh edges (outer, inner and apex) as a reference for new track mesh.

    Cheers!

    No, that screenshot is sketchup... I'm using 3D simed3 and sketchup. I think 3DSimEd3 handles the quads. I hope...

    If I remember it correctly, sketchup generates lots of artifacts on the mesh which are really worky to clean up in max... In matter of fact, everything looks great in sketchup, but are big mess in max.

    I think that could be the root of your problem.

    Cheers!

    No... these tracks were not made in sketchup. these tracks have never touched sketchup except to show the polys to you guys. the widths and such. these are just straight 3Dsimed3 conversions from rF1. they were made in 3DMax and worked fine in rF1.

    Figured out the problem. It was with the tracks.

    In the .tdf file there are two settings. RoadBumpAmp & RoadBumpLen

    the offending file settings were
    RoadBumpAmp=0.003
    RoadBumpLen=11.0

    I looked in some of the rF2 made tracks and the setting was
    RoadBumpAmp=0.001
    RoadBumpLen=3.0


    setting these to ISI's settings smoothed everything out.

    Thanks for all your help in search of this issue.

    still a little bit of bumping in the front end through the corner. bumpamp and bumplen don't seem to help this.

    It is the Tracks and the physics of the cars. They do not work the same in rF2. Track surface has to be rebuilt on all rf1 oval tracks as there are not enough quads and it tends to make the track feel choppy! Plus there are some physics changes that are slightly different in rF2 that makes the cars not act right with a straight conversion. Then you have to build good tires for them which is not easy to do.

    PM me sometime and we can talk about Stockcars!
