You don't have to feel pressured to do this at all, it's your choice. Download free auto-rig program to turn static models to 3D character animation and export to Unreal, Unity, Blender, iClone, Omniverse, Maya & 3ds max. I don't know if you're the right guy to ask, but if you're willing to make this for me, then thanks alot. It doesn't have to be completed straight away, I've got loads of time, so feel free to do when it would be most appropriate. Is the model rigged? If not could you create a realistic model of a Bugatti Veyron (or any other cool Bugatti car) that is rigged (so probably just wheel rotation, door opening and closing and windscreen wipers, I don't want to ask to much of you) and is downloadable in a format that is uploadable to Unreal Engine 4? Sorry for the tall order, but it would be much appreciated if you did so. Plus, the model probably wouldn't look that good anyway.
I'm far too lazy to make my own model just for a game. There is a Bugatti Veyron model I've found on this site that's rigged but looks no where near as good as yours. I'm really struggling to find good car models that are rigged or at least have the wheels separate so I can have rotating wheels or at least some form of animation on it for my game.
