Yeah if bumps are big and affecting the road edges, then it is not going to be easy to alter them, as you will have to also alter mesh positions which is interacting with the road edges. Small local areas might not be super difficult to fix, you can also try some artistic solutions like mask little gaps with some transitional objects or so..... But back to the main point, I don't think that S397 should, or would bother doing that. It is not worth it. It is still laserscaned, and differences will be negligible. Also IMO in real life bumps aren't so great because they are breaking and bending stuff, also unsetting the cars and "helping" some accidents to happen. In simracing there are no such problems. Laserscaning after all is just big label, so far S397 proved it with Sebring that they go a bit more honest with that. Just taking Nordschleife as pure example, other titles has it "repaved" already. They really aren't actually using full resolution of point cloud mesh (it would be way too crazy), they probably aren't even using actual point cloud mesh for road (or are they ?), most likely they just lay new mesh on top of it edit and subdivide it and then applies it function to follow shapes of the actual pointcloud mesh. Anyway, thats the most logical way to do it. At this point it is important what is the resolution of road mesh, it could possibly be totally skipping some important features picked up by laser, many other things may happen such as testers or devs themselves might not like the feel, and smooth it out artificially. One more big thing about Nordschleife is the amount of different tarmac types through whole circuit and the grip is not the same, in the OP video they says that they will not lay very grippy tarmac, to avoid even larger grip differences. Oh some more interesting stuff. In rF2 you would like to have road mesh in neat geometry, rather than random noisy mesh, because of real road technology you want to have rubbering or drying to appear natural. It would not be an issue with much higher resolution of the road, there is also such discussion in these forums. Also with higher resolution it would be possible to get a drying/rubbering tracks for individual wheels rather than whole car path. By the way, by looking at nords and sebring previews you can see that road mesh resolution is crazy, I wonder if they actually are making it so crazy, or they just somehow has pointcloud that smart that it would rectangulate (and separate as in the image bellow) the mesh of the road ? It looks like ~5cm resolution, thats pretty huge. I don't really think that such resolution comes to simulator, but also why would you rectangulate the point cloud ? Also interesting stuff about physics refresh rates is that rF2 refreshes tire calculations at 2400Hz, thats insane and unbelievable. To illustrate that - it is something about each 5cm of travel at 360km/h that would be each vertex of the mesh from above image, maybe slightly an over kill ? FFB is at 400Hz iiric. Recently I watched really nice video, which shows so nicely how actually bumpy the track is, and no sim yet has done justice for that: Beautiful video, I think it is best to observe bumps from exterior videos, onboard videos ar not showing them so well.
