Windscreen breaks but bullets hit an invisable wall and dont go though

[PatBooche]

Hi All

Thanks for taking the time to have a read of the following issues i have.....

So i have a vehcile model, currently the windscreen breaks but for some reason the bullets dont go though, the side windows break and i can shoot though them byt not the windscreen, its like there is an ivisable sheild on the front windscreen.

I have uploaded the vehicle to Zmodler and check over the model to see if there is something is attached to the body shell etc but its not, just the windscreen only, nothing else.

I cant for the life of me work out what it could be, is there something in the vehicle meta file that i can look for or add to resolve this issue?

Cheers
