im not kidding guys unfortunately
how can animate a wheel not only in straight line but when i steering my wheel left or right the wheel doesnt rotate , so basically my problem is that - wheels doesnt rotate when im steering left or right and no matter how hard i search i didnt find any tutorial, most of the tutorials are for a wheel that moves in a straight line which is quite easy to do
and others is a car that follow a path , but non of them its for what im looking for
if anyone can help me i will highly appreciate !!!
You need two empties per wheel for that. Empty_steering and empty_wheels.
Put both of then exactly in the center of one of your wheels.
Parent empty_wheels to empty_steering.
Parent your wheel geometry to empty empty_wheels.
Animate the wheel rotation with empty_wheels and animate the steering with empty_steering.
This way empty_wheels is allways in the object space of empty_steering which means that empty_wheels allways “thinks” that the direction of rotation is the same as it is facing.
and with bones? im using bones for my mechanical rigging
Should be the same principle. You need the wheel rotation to be in the parent space of the wheel turning.
It’s all explained here:
Enjoy!

PS. This is not the hardest thing to do, but I agree it is not easy… Try rigging an epicyclic gearbox for example, or a steam engine’s valve gear, to name but two…
Take a look at Clockmender’s site. He does a lot of mechanical rigging. Look at the one for the Bike on his site how he did the wheels.
Thank you guys , a lot of helpful links ,time for reading !!
