Glitch behaviour with high speed object

Hi,

I’ve an issue with my blueprint vehicle, indeed when this object is at high speed it has a strange behavior, like it collided with something. Look the video bellow.

Can someone help me ?

Hey there, have you tried switching on CCD (constant collision detection) for the colliding objects?

Yes and this is a bit better with it,but there is always that.
While i’m writing that sentence i see something bad, the green number next to “Central” is the high between the ground and the cube is not supposed to changed because everything is flat.
I going to check something inside my blueprint.

Solved I had some very bad behaviour with Physics Sub-Stepping activated. After turn it off, everything returned to the normal.
