noxtech

Hy, have builded terrain then brushed mountain and then started to smooth and it created auto more terrains with same sice just x,y cord. little diferent. then i deleted them coz it lookt like glitch or something like that...
and now i have strange bug i think.
Here you see how its felt into terrain:

and here the edge:

Around/on mounten work ok but when i start go from it at certain distance its drops down.
but just with scorpid.
So can some1 tell me how to fix, what problem, and maby i done something wrong?

Did you ever resize the terrains with the gizmos? The only time I've seen collision issues with terrain is when it's resized or moved- there are usually holes in random spots where the collision is non-existent or under the terrain.

i moved it to center it. so this is the problem?

and terrain size was 800x800 i totally new to this, but i readed alot forums so getting to optional point. But still ciurios to know what issue. And i had remade this map few times and same bug + when i brush mountain (REALLY hight) it makes more terrain actors. So i thinking maby it can be from that side?
