This is made for Unreal Engine 4. If you're using Unreal Engine 5, it will not work by doing exactly the same things. UE5 uses different vehicle systems and components. Also, Unreal Engine 5 Chaos Vehicle Pawn supports n-wheeled vehicles, so you should be able to make 3, 2, 5, etc wheeled vehicles by using it without using a separate component for that.

This tutorial was made for Unreal Engine 4, are you using Unreal Engine 5? Unreal Engine 5 uses different vehicle system, so I don't know how much of this can be applied to UE5.

@@ContinueBreak @ContinueBreak No, i still using Unreal Engine 4, i tried many ways but, same results for all, the wheels falling under the floor. It's really make me mad . Thank you for the fast reply.

Did you rig your model using my blender vehicle rigging addon? Did you set your unit scale in blender to 0.01 before exporting your model?

@@ContinueBreak Yes, I did everything as your tutorial on my own mesh. The problem it was wrong armature axis when i export it from Blender. Now its working properly as well, best tutorial, best communication. Again, from my heart THANK YOU SO MUCH.

Chaos vehicles in UE5 should support 3-wheeled vehicles now, so I suppose that this component might not be so actual anymore. Usually, people complained that you had to enable PhysX vehicle plugin for UE5 to have it available in UE5. If you took my example project and simply opened it in UE5, then it will not probably because there's no PhysX plugin enabled.

@@ContinueBreak I just downloaded your finished project files, loaded it up, and you're right. The physx vehicles needed to be enabled, else compile errors occur because it can't load the simple wheeled component. However, even after enabling the plugin, I am getting the same results as when I built mine from scratch. No throttle or steering controls are active, and the vehicles start leaning. Odd! I wonder if this is a UE5 bug, or if you have to set up vehicles differently. Anyways, if you figure out how to get this simple component vehicles working in UE5 I'd love to hear how you got there :)

Default UE4 vehicle pawn only works with 4 wheeled vehicles, that's why you didn't get it to work with a motorbike. I don't know a solution to your issue. I would probably search if there are some UE4 motorbike examples or just search for how motorbike physics works and then try to replicate that in UE4.

It's quite complicated but you would have to go into relative rotation physics I imagine. I have been making some physics but it gets to a point that it is quite limited unless you build everything. I have some physics that would work for a superbike for example with limited roll, roll more on x axis with higher speed etc.

I just tried to rotate one wheel to the sides with a 20 wheel vehicle and it worked, so I assume it should work. Wheels are rotated when it moves forward and backwards, that's animated by anim instance, so that should have been enough of proof that it works with 20 wheels. That rotation also is done by anim instance.

@@ContinueBreak You're absolutely right. I tried it with a six-wheel vehicle, and the middle wheels weren't turning. I must've done something wrong, because when I tried it again today it worked just fine with the standard setup in the anim blueprint. Thanks for the reply, this video helped me quite a bit because I didn't realize that the other simple vehicle component existed or had the functionality I'd need to make a vehicle with >4 wheels.

In UE5 instead of the Options button, there's a gear icon on the right side of the search bar.

@@ContinueBreak Found it, thanks!

It probably keeps turning cause of inertia not cause there's torque added to the wheels. Physic simulations, especially ones that are used in real-time in game engines, will not work as things work in real life. It might be some inertia calculation issue or something like that. Maybe it will stop moving after several minutes of rotation, and it goes for so long cause there's not enough drag calculated in simulation or something like that. Maybe you could fix that issue by changing some settings for the movement component or wheels, I don't know. Or you could try using UE5, which uses a different physics system. Maybe you will not get that issue in there.

@@ContinueBreak Thank you I will try to play around with the component and the wheels numbers then

Did you export model from blender with the correct export settings? continuebreak.com/creations/ue4-vehicle-rigging-addon-blender/ You might have "Add Leaf Bones" setting checked.

@@ContinueBreak it turns out I didnt drag the skeletal mesh over the root component to make the mesh the parent

If you mean, will it ride to the location if you use Move To node, then probably no. You'll need to add additional logic to get it working.

If it's on roller skates, why not just use animations that he's riding roller skates and use the default character movement component? Or if it has like vehicle bottom, then why not just put the top part of it on the vehicle component as a character?

You could try to change values in wheel blueprints. Change the center of mass offset for mesh, adjust the mass value in the movement component, there are a lot of things that you can try to change.

@@ContinueBreak thanks for your advice, i'll try that

Your blender project might not have set a unit scale to 0.01 or you don't have applied scale to your model. Have you tried to use the addon I made? continuebreak.com/creations/ue4-vehicle-rigging-addon-blender/ If that still doesn't work for you then DM on socials or contact me in discord.

I just checked in UE5 if you have the PhysX vehicles plugin enabled and add a simple wheeled vehicle movement component to the blueprint, you can get a set drive torque node from that, I didn't test if that actually works. I could not find PhysX plugin in UE 5.1 version plugin browser, so they probably have removed it. But it looks like they have added their own chaos wheeled vehicle movement component, where you can adjust individual wheel brake and drive torque by using a set drive torque node.

@@ContinueBreak Hey, thanks for replying. I just activated PhysX on UE5 and it didn't seem to do anything. I'll turn it off and migrate to 5.1 to see if I can get it working.

Set throttle input to 1 at the begin play event.

@@ContinueBreak Great Thanks :D

I think he's using Speechelo or something similar

Is your vehicle front pointed towards a positive X-axis in the blender and UE4?

@@ContinueBreak .Yes this was the first thing i looked at after checking collisions of course . They do roll forwards like normal but then fall sideways .I have tried unreal 4.17 / 4.23 / 4.25 / 4.26 I have the same issue in all of them .I have also tried a plugin for blender which automatically adds bones and rigs the vehicle and still have the same issue..:( I have now added a hover component and have a flying car...It is 2020 after all

If you could send me your UE4 project files, maybe I could look more into it and fix your problem. Haven't heard about such an issue before.

@@ContinueBreak Oh you are the guy who made the plugin..Lol i didn't even realize. First of all thanks for the plugin . And secondly i do not have the file anymore .But will recreate it in the same way later . Its more than likely something i have done wrong im not too smart lol.Thanks again

@@mrstarfire9336 Hello, I have a same issue :( did you find any answer? I don't know why my wheel always roll....

same here, you found solution?

Hey, how did you do this in UE5? Here I can't seem to find the Set Drive Torque node anywhere in the blueprints, and I don't know how to substitute it.

In Unreal Engine 5 it's named wheel controller. Also, this tutorial is made for Unreal Engine 4 which uses Physx physics for vehicles. In Unreal Engine 5 they are now using Chaos physics, so all vehicle-related components are rewritten and this tutorial will not fully work, you will need to do some additional work to make it work. One of the things that you need to change is the External Torque Combine method for wheel blueprints to Override, to make the Drive Torque nodes to work and you need to have Set Throttle Input value not 0. There might be some other things you need to do to get this working. Unreal Engine 5 default vehicle pawn now supports N-wheeled vehicles, which might be a better thing to use if you want to make a vehicle with more or less than 4 wheels.
