Checking the files from Dragons Dogma I noticed that the normal maps are all funky looking.
Seems like they are storing their normal map data a bit different from a regular normal map set up.
It looks like the use the alpha channel instead of the red channel and the data in the green channel is inverted (Using maya).

This set of actions simply 'fixes' it to something we are more accustomed to and reverts it back to the DDDA set up.

So anyonethat want to modify or do texture swaps can use these actions to quickly set it up properly.
