I can't find landscape 'sew' button - stupid me, please help :D

if your talking about connecting two landscapes together then i dont believe there is a button to do that.

Hello

This is very basic thing working on terrain, and I can’t believe it don’t exists in engine, so I just can’t found it in editor and over the google.

Please help!

Exactly this button. I understand, for big landscape it should be just done correct, but I have smaller landscape parts on level and this is important. I still have from other editor habits, this is very old editor…
