I’ve spent a while on this now trying to build this cart in Unreal Engine 4.27 to work with the chaos vehicle system.
At the moment, I have ported my cart made of 5 parts (chassis & 4 wheels) from Blender with 5 bones.
I set the wheels to kinematic, body to simulated. It just falls apart like they aren’t connected with the wheels disappearing in the physics asset tab.
I added constraints between the chassis and wheels and the whole thing becomes locked like simulate physics is turned off.
Hi @Scalemate ,
From what you describe, the vehicle falling apart could be caused by an incorrect hierarchy in Blender, a collision issue, or a Physics Asset that was generated incorrectly.
And from what I can see in the images, it makes me think that the Physics Asset may have been generated incorrectly, since the wheel bodies should appear more like this.
(This vehicle is from one of Unreal’s built-in template examples, which is why it looks different.)
I’m not sure how you set things up or handled the export from Blender, but I’m leaving this video here because it explains step by step how to add vehicles to Unreal Engine 4 from Blender. I think it could be useful for comparing the configurations and the steps used to import the vehicle correctly.
