I do not understand Precombines

[Guest]

There are several places where Precombines show up, I do not understand what this is or why it happens. One example is the toilet in Fizztop grill, Nuka Ride, (see Pic) there are 2 toilets, one over the other. I do not have any mods altering Nuka World as they usually mess with Nuka Ride, so why does this happen?

I had the Previsibines Repair Pack, but could not see an improvement to anything, still two toilets, two pool tables, so I uninstalled it.

Another location is Atom Cats Garage, two pool tables, one sticking out of the other, again no mod altering that cell. No pic.

I am just trying to understand, not change things. 

Thanks for your reply.

You can check what is altering precombines. Open modlist in xedit - right click in the left pane -> Apply Filter -> "Only has precombined mesh"

 

Tick "by Has combined Mesh" and "Only has precombined mesh".

 

You can then see what is making changes.

 

Alternately Boston FPS fix will sort many precombine problems, but probably not ones you have caused yourself!
