Fixing boxcoll (green boxes) after zmodeler export (Hashes)
Mafia II vehicle itemdesc has two hashes. First hash is used to link frameresource file, second hash is used to link prefab file. Zmodeler 3 does not correctly save the second hash when exporting models that have a BoxColl type (green boxes). This, in turn, causes this type of collision to stop working in the game. In order to make collision work in the game after export you must manually edit the UInt64 values to these from vanilla car file in a hex editing program (in my example I use HXD).
First hash (frameresource) starts at 00
Second hash (prefab) starts at 0A or 10
Prefab itemdesc hashes can be found in Unk4 in CollisionVolumesCollection (DeformParts), you can easily swap collisions between cars thanks to that.
*Itemdesc filename can be found in frameresource under hash in ItemDescFileName section
To make it easier to edit these values I have added vanilla Uint64 values of BoxColl itemdesc files below:
| Name | Prefab Hash |
| Box_coll06_Collision | 17610561133039336815 |
| Box_coll07_Collision | 1847790794406838400 |
| Box_coll08_Collision | 1459014791424620140 |
| Box_coll09_Collision | 15424262848899757835 |
| Box_coll10_Collision | 16757454051114746494 |
