Vehicle immune to explosives nut not bullets?

[USweapon]

ok im having a problem here when making vehicles. the vehicles work great but explosives cant damage them. bullets are the only thing that can damge riders in the vehicles and rockets and other explosives dont damge them at all. i think its something with the collion model i made.

I ain't an expert but, I think you should go over all your files (collision models and tags) see if that works:D
