The burned texture after an explosion didn’t apply properly on the car. The bug happens sometimes. It only happens on explosions from the landmines or missiles. I play on mobile. I can’t tell when the bug appears but it happens as soon as u drive into an explosion by missiles/ landmines. My friend was also able to see this bug so it wasn’t only on my screen. I have a short video that shows the bug.
You have underglow equipped. Underglow, you see, isn’t some kind of dark magic. The glow comes from a transparent rectangle; and that is the rectangle shown in the image.
