Chaos Motorcycle/Hoverbike won't move?

Astaraa · October 13, 2022, 5:01am

I’ve been banging my head against Blender all day learning to make bones, so maybe I’m hallucinating, but my vehicle won’t move. I’m making a hoverbike, or essentially a motorcycle with no visible wheels. Seeing if this will work better than one that actually does float. (In the process learning about this system for vehicles with visible wheels.)

Any help would be appreciated. I’ve hit a wall at this point.
As far as I can tell everything is in place.

Bike appears to be off ground only touching the wheel collisions, so nothing appears to be snagging.

Physics asset. Wheels collision disabled and set to kinematic, as instructed.

Wheels and torque set in vehicle blueprint.
Skeletal Mesh is set to simulate physics.

Front wheel - set axle, size, friction force, and steering.

Back wheel - set axle, size, friction force, and engine/brake.

This was my main reference along with another motorcycle specific tutorial:

Hey Astaraa,
These tips worked for me:

Set Blender Scene Unit Scale to 0.01 (may have to scale everything up by 100.0).
Vehicle body and wheels are all separate objects.
Make sure to apply rotation and scale (not location), and that the x-axis corresponds to the forward direction.
DO NOT USE AN ARMATURE (learned this the hard way). It’s way easier to just set all the wheels’ parent to the vehicle body.
Export to FBX: set forward to x-axis and up to z-axis.
When importing to UE5, check the box “Skeletal Mesh”
I believe the rest of the steps you described is the same thing I did.
Good luck,
-Ed

Hello again,
After I wrote my reply, I tried it out… using “Empty(s)” for wheels… and it worked. Now I have a little hover-craft-looking-thingy.
Best of luck,
