You are forgetting tolerance, with heavy vehicle you have more tolerance, meaning larger range of values work, what is 1kg in 10 000kg vehicle for example, but with 700kg vehicle 1kg is a lot more, percentage of change in each node is different, that is when we have same number of nodes of course. So you can setup values further from optimal and it still works, but with less weight you can't make same kind of changes, they have to be smaller changes, but if you manage to keep relation of spring, weight etc. then all should be well of course, but there is that big if. Anyway it just takes lot of practice now that you know these basic steps and how different values affect to structure, there really is no substitute to practice here I believe and boy do I need lot of that until I can get my NB structures to work well, there is so much structural engineering part that needs to be learn.
AGREED 100% tolerance! And yes working with physics engines requires alot of knowledge about engineering,math and computer science which makes you wonder how the devs know all that,they cant just be computer scientists. It woutld be nice if they post in this thread https://www.beamng.com/threads/how-...-how-vehicles-should-deform-and-handle.55809/ Anyways i really appreciate all the replies and information ,you guys have been extreemely helpfull!
