Hi everyone,
I recently ported a motorcycle project from UE4 to UE5, and it’s using Chaos Physics now instead of PhysX. In UE4, the motorcycle’s behavior when colliding with objects at high speed the joints would move slightly or project a bit, as expected. However, after porting to UE5 with Chaos Physics, I’ve noticed an issue: when the motorcycle hits something at full speed, the joints move or project much further than before. It seems like the behavior has become exaggerated, and it feels unrealistic.
The bike is created in BP with static meshes and physics constraints.
I’ve attached a video that shows the issue, where you can see the joints behaving more drastically when colliding at high speed.
Here’s a quick breakdown of the issue:
- Motorcycle was originally created in UE4 with PhysX physics.
- Ported to UE5 using Chaos Physics, which causes the joints to react much more than they should during high-speed collisions.
- The result is that the joints appear to move or project a lot further than they did in UE4.
Does anyone have advice or a solution for fixing this? Could it be a setting in Chaos Physics or something I need to tweak in my motorbike setup? Any pointers would be greatly appreciated!
Thanks in advance for your help!
