I love the rig but where do I find rigfx.sqf?

where the heck are the mission files

You can add compositions via add-on but I'd rather not go down that path. BI have said they want you to be able to have compositions directly on Steam Workshop at some point, once they get around to it I'll likely do that.

There's a few mods on the workshop with compositions already. Unfortunately I'm unsure as to how all that works though. Good luck, and good mod!

@see you...
The download is a multiplayer mission with the oil rig in it. You'll have to unpack the mission to get at the objects, I've updated instructions a bit to make this clearer.

@Rector
I thought BI hadn't gotten around to implementing steam workshop support for compositions yet. If they have, great, if not, I'd definitely put this in as a composition when then do.

Just a suggestion, is possible. Perhaps try to turn this into an 3den editor composition so it can be easily added to missions?

Where's the oil rig found? You just "copy all the objects" from where?
