300Km/h Pawn cross the landscape

If you make a pawn, (no character pawn) and add to root a capsule collision that simulate physics and do some kind of movement system or something like the Epic mountains demo in a landscape of about 10x10Km using a 2048 Hiehgtmap texture and scale it to 500x500x500 when you go at hight speed and don’t touch nothing the pawn cross the landscape always, only collide with CCD enabled.

Hi Hevedy,

I’m going to need some clarification. Are you saying that the pawn falls through the landscape or doesn’t collide with mountains and such at high speeds? I tested this in a new project but I couldn’t get those results.

Could you provide a small test project using one of our templates?

Is like if it just cross the landscape walls like if the landscape was a ghost, I’m using some kind of edited version of the Mountains demo flying thing but with a capsule collision as root component and no meshes. You go fast at about 300Km/h with that to the mountain wall and just cross it (Note my capsule component is same radius and height 22)

I tested this in the Landscape Mountains project and was able to reproduce what you described. What you need to do is increase the landscapes Collision Thinkness. By default it is 16. Keep increasing it until you can no longer push through the landscape.

When it comes to physics interaction at high speeds, things can sometimes get a little weirld. You don’t see this same behavior with the Character class because that capsule is not actually simulating physics, it’s ‘faked’ through the character movement component.
