Ok im having a problem with bullet holes, my bullet hole decal is fine and all that but… when i shoot a box or barrel i want it to attach so that it is “part of the box” if that makes sense…

2 options:

Replace the box/barrel with a “shot” box/barrel at the same position. I.e. a prefab with the decal already applied.

Or, parent the box to the decal using this:

void Parent( GameObject parentOb, GameObject childOb )
{
  childOb.transform.parent = parentOb.transform;
}
