I have no idea how these files work and what decides where they are located in-game so I kept recreating the mesh to figure out what works, in each time I don't manually create it by hand it becomes invisible, and when I followed the examples and instructions by lipsum, It does work but it's mis-aligned. Changing the location of the mesh doesn't affect this, the only thing that does is recreating the whole thing or changing a small detail in the edges of the mesh which caused it to change significantly.
This is what it looks like when I got it to work, changing the mesh position doesn't affect the in-game result:
And this is what happened when I changed a few edges and slightly changed the geometry:
