Is there a tool to open the models of the game to edit them?
Well, if you want to edit them so that you can use them in your VU mod, it’s not currently possible, but with Rime, you will be able to do that in the future.
If you just want the 3D assets so that you can use them in other engines, maybe you can check out p3dm.ru.
i use them in Unreal Engine 4…but there is a little bit a problems with them,they are ripped wrong way, M1 has wrong turret for some reason,and models doesn’t have a “normal map” in BF 3,apparetnly dev’s did that for performance. Those models are considered todays as low poly.
