It looks randomly, since i posted i not had again the issue, but if happen again i will check the effects or remove/add again to see if fixes.
Btw I detected something weird with the skidmarks not matching the tyre, so i enabled gizmos:
When more speed, more difference between the real visual tires and the physical ones. What happens? It does in all cars i tested. I thought maybe was something i edit so i downloaded the FGearExample and same.
This causes the skidmarks not match the visual tires and other collision stuff due wheels are on XYZ due speed, but on collision it goes to the correct ones and if there is an obstacle it kicks the car to the sky.
So, why this happen? Anyway to fix this issue?
Edit: This is a Plugin bug or PhysX related? I mean, maybe with chaos it does better ¿?
