I was wondering, how do you make a union with a script. Wouldn't the way to make a union be:
Instance.new("UnionOperation")--pretty sure that's the class name
But how do i shape it the way I want? How do I put parts into the union. I don't think making it's parent the union will work.
You can only complete union operations from the command bar or from a plugin. You can't do this from a normal script or local script.
Take a look at these wiki pages if you want to know how
