Will do. To make sure I'm understanding correctly, the radius is the width of the terrain affected by the tire correct (both up and down)? So 3.5 feet being effected by an 8 inch tire seems on the big side already or am I missing something? Or just is on the small side for what the game can handle?

Sounds like I have more testing to do

That was what I originally thought - that the only effect was the tires directly moving dirt around through roost. That's why the original roost based erode algorithm worked so poorly. I think it was actually you that straightened me out on that. There was a video that someone posted (I thought it was you) that was a fixed camera filming a berm. Every time a rider hit it you could see the entire berm move well beyond where the tires touched it. It was visibly moving several feet away from the direct contact and I'm sure it was imperceptibly affected even further than that.

So the new system tries to model it more like clay being squished around. Imagine you draw a grid on some clay and then push the center of the grid in some random direction. The radius is the max distance where the grid would be distorted by the force.

This scales the force from the front wheel. Use lower values to prevent braking bumps and less berm on corner entry. Default is 1.0.

Yes, this setting is probably the best setting in erode. Turn it down and turn up displacement/depth and get sick bumps without giant ruts that trap you in. I think it'll completely transform national erode.

My bad, that was lateral scale, now front scale.

Do you have any ideas or a direction to go in to make that exit rut (the pink tile) form a couple more lines? You can see where the lines want to form, they just aren't there yet.

Here's the settings for that tile
