Take a look at this http://obse.silverlock.org/obse_command_doc.html#GetBoundingRadius
Thanks, but I was specifically after the exact height of the model. Seems that's not possible. Luckily I found that the mod I was editing had already hardcoded if statements to get the height based on the model id or something. So now the mod sorts by height and it looks beautiful ^-^
On a side not, the wiki is wrong, it says that to store a user function return value, you do something like
Let someVar := Multiply 5 10
But I kept getting invalid opperands on the :=, and it took me an hour to figure out that I actually needed
Let someVar := Call Multiply 5 10
May seem very insignificant, but took me a long time to figure out, as there's not too much information on this
