We are creating a high fidelity, Sci Fi shooter game in Unreal Engine 4 which requires the player to use a plastic gun controller. We have a 3D model (.fbx) to match the gun controller. We need to modify this model to suit to the four different gun types that are in the game (that is, we require four models). Please carefully read the attached brief for more info. We are keen to develop long term relationships with 3D artists as there will be plenty of future projects that we will require help with.
