Aye its a bummer , i cant believe Bis are allowing all there wall sections to be unhidden and hiding on impact , it just seems so backwards , i know there a bit Heath robinson at times, but i think there using texture and hiding geo lods there no other way i can find and i have even been in the hex editor.
I guess i will have to use Eh but the way bloody Hit work i will have to use dammage and the big problem with that is , bullet hits or more over launcher hits have a hit radius and it doeesnt take into account that if it hits a wall , it should not pass the damage through 8 meters , even if i create a hitpoint and put passthrough 0 , the bloody hit radius will over ride it and blow everything out lol.
Looks like a Big job ahead.
