Well, after loot of pain and try and error, blender, modo, and learing basics things, i was able to get this working with out bones.
Now, I need to make a question.
What the differences with a rigged vehicle (and with a rigged AND weighted vehicle like the unreal examples).
I took a look at this: https://docs.unrealengine.com/latest/INT/Engine/Physics/Vehicles/DoubleWishboneVehicle/index.html
And as far as I saw, the standard vertical movement produced by the WheelHandler is just fine for my full body vehicles, however, what are the limitations that I could have on a future?
