I'm inspecting ways to smooth things correctly in Blender. I've created this structure out of a cube and displacement modifiers applied to every side. As you can see, results bear some grid artifacts:
My question: is there a way of smoothing that out of the usual subsurf modifier? I've used procedural textures over vertex groups to create displacement. Maybe there is a way to obtain smoother geometry by using finer textures in the beginning... I could resort to some smooth modifier, but there are three of them and the difference is not really clear to me... Thank you in advance.
