Now in Nuke in your CornerPin's paramaters push the button :)of animation menu of the first corner and select File/Import IFFFSE.
In panel pop-ups you have to seelct one of the four "corner" files exported from mocha. Start At parameter is a frame which animation starts from. It takes from your project settings by default.
