As you see the car seems to rock back and forth in-game (depending if you’re going forward or backwards) and I don’t know why.
I’ve tried adjusting the center of mass, and changing the mass or the collision boxes, but nothing works.
Any ideas?
The wheeled vehicle pawn.
The bone tree. With the body as a parent.
The 4 wheels in the “VehicleMovement” component are set to use the correct bone names of the wheels and a simple Vehicle Wheel class with changed dimensions.
Event graph.
How are we moving the car? Can you show the hierarchy of the actor?
Still not fixed
At this point it’s probably best to take a whole different approach
I know it’s been over two years, but maybe this might help someone else.
I had this same issue, in my case it was caused by using the wrong default scale in Blender. Following the last section in this guide resolved it for me: Driving Around: Exploring Chaos Vehicles | Talks and demos
"Blender and Unreal have an incompatibility regarding the default scale when importing an .fbx model, so in order to import it properly, we need a workaround before exporting a vehicle Skeletal Mesh from Blender. Do as follows:
- Select your Armature object, press S for proportional scaling and set it to 100.
- Press Ctrl+A and apply the scale transforms to the object.
- Head to Scene Properties > Units and then set Unit Scale to 0.01.
- Export your mesh as .fbx."
