Firstly, as many have already said, these are scratches. Secondly, this is the car pollution system. And thirdly, these are liquids leaking from the engine after a collision, such as: antifreeze, brake fluid or even gasoline. I understand perfectly well that it will not be easy to implement this, and in general these changes will most likely have a very strong impact on productivity, but perhaps in the future we will enjoy such changes.
lmao --- Post updated --- car pollution system sounds insane you want to simulate global warming in beamng? i think you meant smoke... --- Post updated --- you mean something beamng already simulates car parts can break off if theyre supposed too only debris maybe it could simulate is the enviroment which would be a lag heaven
