I am working on my Road Grip Editor mod and there is this one parameter of the ground_model class that I really don't understand which is called "shearStrength". It seems to randomly change between some very random number (depending on the instance of the game) and zero when I get its value (here's an example for ASPHALT it will output the same for any surfaces): Code: print(be:getGroundModel("ASPHALT").data["shearStrength"]) If I clone a surface's ground_model which seems to have some depth to it and try applying it to itself with be:setGroundModel(), it will completely obliterate any vehicle. But if I set "shearStrength" value to zero before setting the ground_model, there is no chaos. This sort of process is what I use to reset the surface's groundmodels. The wiki page has no idea what this parameter is but the BeamNG documentation page seems to be confusing flow behavior index for shear strength. :/ Does anybody have an idea what this parameter does? Thanks in advance!
