Weird cockpit vibration

That was exactly what I was looking for,TNX

When taking a corner, doesn't matter if it is hairpin, or just slow and easy, the entire cabin shimmies -- vibrates erratically from side to side in a stuttering manner. This does not happen in 1.8.2.5. This effects both stock trucks as well as mod trucks (Volvo VNL 780, Peterbilt 389, etc).

Today I noticed it too on a moderately sharp bend on a shallow incline. And as you said, it appears to be new for 1.9.

For anybody wanting to try it out. It's a small and quick motion that feels somewhat like a quick version of those suspension test tracks where your left and right wheels drive over small bumps one after the other. And as TruckSimFan says, this also causes the top to go side to side a bit.

It's no a huge problem, just a bit annoying to look at.

Maybe a more detailed model is needed for the corners? Less polygons = less flex, even more so if the polygons are quads.

There are not that many sectors that make up ETS2 corners, & if the collision model is based off the corner model (or has less sectors than the corner), then you are going to have this problem on uneven ground (ie up or down hills). This kind of problem is not seen on a flat surface as the model/collision model is flat. The steeper the incline/decline the more "stepping" you will get between the polygons.

The answer to this problem (IMO) is, triangulate your polygons or add more sectors to your curves.

This doesn't sound like something to be fixed anytime soon. It involves the changing of the stock maps?

cheers,

It used to work fine on the current road geometry with the pre-1.9 physics, so it may just need a little tweaking.

I just did a long drive in 1.9.20. I avoided motorways to test this and the effect is still there.

Lets hope so

Agreed. The movement is very small yet disturbing, noticeable in curves with inclines or declines, not matter if on a motorway or a smaller road.

I don't wonder some folks may start feeling motion sickness because of it.
