Guys,

Why I'm getting this weird bump projection. I couldn't figure it out what I'm doing wrong.

The curious thing is that when I open a new scene and apply the same noise over a sphere it doesn't happen.

You have your materials projection set to UV but you don't have any UVs. Set the projection to cubic or spherical and you should be good.
Also, you may need to tweak the phong tag if you're still getting hard edges.

Hi, thanks for you help.
Well, I didn't expect it was considering UV mapping for procedural textures. I though the projection was being set from Noiser shader in the Space parameter set to texture.
About those facets showing up, I couldn't find a way of getting rid of it. We don't have phong issues here, in the viewport th mesh is ok.
Something weird is going on here, I still believe.

It seems not to work properly when you have small objects. Take a look, 20 cm sphere, UW projection, not an issue at all.
Procedural textures, they do not need UVs, that's the benefit of using them.
