I’m trying to set up a Chaos Vehicle from scratch, since all the ones in the demo project are 4 wheelers.
I made a simple bike in blender, exported as FBX with a skeleton for animations and whatnot. I’m able to make it look like it’s doing whatever I need via the anim blueprint (leaning, wheel rotation, etc), but I can’t get it to move via the chaos vehicle setup. I was previously just applying new velocities manually, but ultimately I want more realistic vehicle speeds, via gravity, resistance, and torque.
My vehicle BP has the Wheeled Vehicle Pawn parent class:
My Skeleton Mesh has Simulate Physics turned on and the default values otherwise.
My event graph is setting the chaos vehicle component’s throttle and steering input:
And my anim class is using the wheel controller:
It’s doing some other stuff too not pictured, but even if I connect the output node directly to the end and skip the rest, the same nothing happens.
The bike’s physics asset looks like this:
Settings for all three portions look the same.
Here are the bone names (and applied physics shapes):
And the wheel setup:
Here’s the Wheel Class
I’ve tried with and without Mechanical Sim Enabled with and without custom torque curve, no difference.
Every resource I can find seems way out of date, or incomplete, and I can’t figure out why it’s not moving. Any help would be appreciated. LMK if you need any more information about anything in the project.
