Sorry to ask about Nif Scope here if it is the wrong place, but I did not know whether this belonged to Mods or maybe Construction Set.
I have a problem that a mod introduced emerald mesh wasn't really centered I suppose, and consequently floats over everything I place it on. Looks like this:

Luckily, I still had nif scope around from Skyrim modding time, but most things I did there was linking other textures, or remove weird plates or extras from some armor and such. I found the emerald.nif which looks like this when open (way bigger entry than other gems for some reason):

...but I have no idea where the actual world coordinates can be found. I see shape values, but those are relative, not absolute, and pretty much the same as sapphire and topaz models. I guess I could just copy a sapphire and tint it blue, but I would rather not if I can get it done cleanly.
