Question I want to create a distorted/deformed object with connected edges.

So the shader I have got is this right here:




I want a shader that deforms anything a little. With just object-position and noise it would not have connected the edges, so there were holes in the mesh. But as soon as I add the rest (which I got from a tutorial) the whole object gets bigger and a cube wont have its edges connected:
Left one is the sphere that gets deformed as intended but it is about double the size than it should be. On the right is the cube which is not working as intended. All the triangles or surfaces should also be deformed.



Anybody has an idea on how to achieve that? And yea, I dont have properties in the shader yet because I was still trying.
