4Wheel extended rolling motion

[wellander]

I have been using 4wheel extended today and I ran into a problem with the simulation. I was driving a "truck" on a nascar track and I got this rolling motion from front to back that grew in amplitude as I went through the turn and that decreased as the rig went "straight".
My guess was that it was a suspension related issue but Then as I changed the settings and hit "resimulate" the car went on for some hundred frames only to suddenly go flying into space. (I don't have fast raycast checked)

The track is created as a lofted shape in Max. It looks flat and clean but when I look at a preview the texture looks wavy and the bouncing of the trucks seem to be in sync with the texture. All in all the mesh is pretty low res as can be expected from a road. If you have turns and banks on a road does it have to be high res? How hi res?

Any idea why the resimulate gives me really bad results?

I can mail you a quicktime showing the result.

Hi Wellander,

I have never heard of this type of problem. Please send your movie and scene to support[at]craftanimations.com so that we can have a look at the scene.
