I am definitely considering doing something like that
I have deleted EVERYTHING on my map. I selected every splines, every objects and deleted everything. The mortar remains.. So it is not an object nor a spline. HOW DID IT GET THERE AND HOW DO I REMOVE IT. Seriously, this is driving me insane, how does a mortar magically appear.. lol
edit: I have found that using the stamp tool (copy paste on a new map) fixed the mortar glitch. Onto the last question. I want to import my atmosphere settings that I saved on my desktop. Where do I put the files so I can load it up?
