Rhino 7 Displacement

Hello Team
I used Displacement’s video on Closed Polygon - for 3D printing. But there was a problem that you can see in the photo. As you can see, the edges of the displaced surface have a gap. Can anyone guide me?

I have converted the model to closed solid by Boolean and I have selected a part by holding control and shift. Then I added a texture with displacement.
Is there a solution?



The only way to have a displaced mesh without gaps, is to have a single closed, welded mesh.

thanks a lot.
But if I do displacement separately, Boolean union cannot be done because displacement is applied everywhere in the model.
