Hi, we made cars in DayZ and found a strange error. As soon as the Penetration armor material, which is presented in the game, becomes more than 7mm, and this is the conditional glass of the car. Then, after the glass breaks, the bullets begin to disappear into the geometry of the glass itself.
But once you make the glass less than 7mm or lower, everything starts working fine.
I talking specifically about materials called "armor_30mm_plate.bisurf" and others.
And yes, the error can be repeated even on a vanilla cars, I replaced the Penetration materials of the game and got exactly the same result as on the mod cars.

Judging by the experience of Arma 3, it does not work correctly. Because Arma 3 also has the same logic of materials and 30mm glasses work well. I even took the penetration materials from Arma 3, because the parameters are the same and nothing. The error is still there.

Just set the glass penetration material to be larger than 7mm and get the same result.
