## LodEdges

```
struct
{
   LodEdge   LodEdge1;  //MlodIndex
   LodEdge   LodEdge2;  //VertexIndex same Count as any of the VertexTable.Counts (odol7)
}
```

### LodEdge

```
CompressedArray
{
 ulong   nEdges; //always zero for type 53&54 dayz o3ds
 ushort  Edges[nEdges];
};
```

Every vertex in the vertaxtable is owned only by 1 face.

These tables are used to join vertices. Each face has got 3 (or 4) vertices that are unique for each face

For each VertexIndex there is a lookup into the MlodIndex

```
MLODvertexindex = MlodIndex[VertexIndex[Count]];
```

Note that compression has not been seen in arma. (not large enough)
