Hi everyone!
I was wondering is it possible to create realistic car movement with reactor and path constrain. While useing reactor gave my some great results moving a vehicle straightforward, I did not understand how to make the toy car turn.
I need to make the front wheels turn and the body and rear wheels follow realisticly while the car is making a turn and useing reactor at the same time.

Any halp will much appreciated. Thenks!

Reactor is OK for virtual stunt cars, crashing and stuff. But not so good for more controlled driving animations.
For following a path, try Loran’s EZ CarRig, it’s free and it works. Also see Joe Gunn’s tutorials, there are a few relating to car animations. There is also one on car rigging in Max’s supplied tutorials.
A couple of plugins to check out, Mad Car, a free one, or if you want to spend some money there is Craft 4 Wheeler. There is a free cut-down version too.
A few options to look into there.
