Philippe Roubal has recently completed both a 4x4 drive system and a very cool looking tracks creator, which leaves tracks wherever your vehicle drives.
After several months and 6 main differents versions alternating Setups made of solid objects and Armatures, with tens of various attempts and variations in between, I have finally built this 6.1 version of my 4x4 Autodrive system, including the Tracks Creator.
The goal of this setup is to provide a system that is ready to use, allowing to animate automatically a four wheels vehicle on any kind of terrains, with automatic obstacles detection, and not using physics simulation : The Game Engine is not used in this setup.
This setup uses a simple and efficient armature driven by four "Altitude Sensors" made thanks to ShinkWrap modifiers.
- Just import your own model of car, wheel and terrain : the system is ready to play.
- Animating the car requires only to edit the curve (trajectory) in top view, and to adjust the speed of the vehicle by an unique Ipo curve.
- A driving character is provided, automatically animated. You can easily edit the shape and materials of the mesh to create you own character that will still be animated if you don't break the Vertex Groups.
- The system also produces automatically tires tracks after each wheel. It allows to create easily animated textures to make tracks after your vehicles in all ground materials : sand, mud, soil, snow, grass...
There's a great video on vimeo which shows both systems in action and Philippe has very nicely put together a comprehensive manual for download here.Â Finally the .blend can be downloaded from this link. A very handy resource!
