Vehicle wheel traces passing through floor

I’ve set up a vehicle, imported from Blender. I am using the built-in Wheeled Vehicle parent blueprint, and using pxvis collision, I can see the black wheel collider wireframe (properly aligned).

However, they are not colliding with anything, including the default cube mesh and geometry set to Block All.

Can anyone help me figure this out?


change vehicles movements- wheels radius

Doesn’t seem to work. This happens with whatever radius I give it, whether really big, really little, or exactly the size of the wheel.
