This mod doesn't have a basket, it's only the bird. The file contains all the animation: death, flail, walk and idle. This mod can be used with AoM and AoM:TT and will cause no OOS. The Roc can still transport units.
To install, place the .brg's in the model folder.
Updated: I updated the ReadMe now there's also how you should install it.
Updated2: I tested it on OOS errors, and no OOS error ocurred.
