If you guys are referring to "SM01 Battle of Midway", then you'll have to refer to it as such, otherwise, we assume you mean the campaign files. Anything SMXX is a Stock mission, left untouched by us for the most part, save to make the ship calls FotRSU compatible. If however, you are referring to the career Battle of Midway file, then there is this:

As for the Shinano, we did find that a few weeks ago and discussed it, and I believe it was mentioned a few pages ago, but s7rikeback has used everything in his arsenal short of dynamite, to blow that silly Halloween costume off the Shinano, and nothing has worked yet. You can either have a good looking hull and then transparent decking and conn, or you can have the psychedelic panteloons and bloomers showing, and a fine deck and conn, but thus far, not both together, unless you delete quite a bit of SH4 functionality from the ship. Notice the wake "in front of" the ship?... very strange.
The ship is not called by the mod, since its only voyage was in November 1944 - an attempt to go from Yokosuka to Kure for final fitting (including water-tight doors), that Cdr Joseph Enright and the crew of the Archerfish interrupted with four of six torpedoes fired... For the time being with this next 'patch' release, the ship has been removed from the mod. It does take damage from torpedoes, and there are no problems with it operating as a ship, but the emperor's new clothes are just too garish. Once the crew gets a new paint job of dull dull grey gray applied, she will be returned to the livery, and a proper "final fitting journey" (with the emphasis on "final") will be added to one of the layers for any wannabee Archerfish skippers to attempt to chase, catch, attack, sink, and then get away safely from...
