“It doesn’t work it a packed game.”
I have had the same experience and reported to epic a while back 
I’ve experienced with getting vertex locations in packaged games since 4.3
If you start a new Answerhub, link me and I can add more info to your report
Please include your pictures and then I can add info, you could also add my code below to the initial post.
For Epic Staff:
Here's the code being used that works perfect in pre-packaged game and does not work in packaged game.
**It seems that using the Render Data / LOD info in packaged game** does not work some reason?
```
Comp->StaticMesh->RenderData->LODResources[0].PositionVertexBuffer
```
Is there an after-packaging better way to get the vertex position info?
Please note the rotation/translation of each vertex is scaled by the FTransform to match actor scaling and rotation.
```
Comp->GetComponentLocation() + RV_Transform.TransformVector(VertexBuffer->VertexPosition(Itr))
```

);
}
return true;
