Ребята, как сделать хороший рельеф(скалы.горы) я ненавижу, что нарушать границы между ними)?
I google translated what you said, and I'm thinking that the problem that you are having is that you are not sewing your displacements together.
To do this, select the two or more displacement faces that you want to be connected in the face edit sheet (you do this by holding the CTRL key while selecting more than one object), going to the displacements tab then clicking the sew button. They should now be connected.
In future, please speak English, you seem to be able to as the title is in English. It's just generally more helpful.
