Simple Wheeled Vehicle component is not attaching Wheel collisions

I’ve been working on this for 8 hours with no success. Please help.

I’m trying to make a drivable garbage truck, and I’ve followed about 3 different tutorials on how to get wheeled vehicles to work, but it always has the same result. The collision for the wheels is just to put it simply, not there, and the wheels clip through the ground and the truck is undrivable.

I don’t expect any answers for at least like 4 months, because my past 2 questions were just completely ignored, but I need help right now more than ever.

You need collision set up for your wheels in the physics asset… generally sphere collision scaled to wheel size attached to the wheel bone

That’s what I tried initially, but it results in this weird outcome where the wheels stay above ground and the truck still falls through. If that’s not the case, the engine ignores the wheel collisions entirely unless I remove the ‘Simple Wheeled Vehicle Movement’ component from the blueprint, which I need to keep in there.

Also, in all the tutorials I watched, the wheel collision was added from the ‘Vehicle Wheel’ blueprint after setting up the wheels in the blueprint. This is why I did not add a collision there.

Odd behavior, seems like a physics asset setup issue:

Truck is still ignoring collisions… but now the wheels are appearing under the truck. Otherwise it’s falling right through the floor again
