I have already reset xform on the mesh. I tried resetting xforms of the markers.
To make things simpler I took the example Turanic carrier and then exported it. I put it in the game and the Navlights and weapons were properly aligned.
I then took the Turanic carrier and scaled it down without scaling down the markers. Then, I moved the two antenna navlights and put them where they should be on the mesh, like so:

I put the file into the game and the carrier was scaled down but the navlights were positioned like this:

I tried resetting xforms on the mesh as well as the navlights and the same result occurred. While the offset isn’t as significant as it is on my custom model, it is still there. I am assuming that this problem is caused by the scaling of the mesh, but I don’t know how to fix it.
