Nonsense projectile collision

Hi,

i have projectil with collision preset Physic actor, and then map where is almost nothing, but the projectile on this map does like nonsense collision, that means it is fliying, and suddenly it changes the direction like in shape of letter L etc, but there is nothing which it could bounce against…

What is this for bug, how could i trace it?

Thanks

L.

Haha !!! Got it :).

Cool… Menu on left - Show / Collision…

Big cubes appeared, it was invisible parents of some tiny meshes…

Cool
