Displacement edge

artifacts.png

Hi,

I have some displacement artifacts on the edge (on the top) of my object. See attached file.

What caused this to happen?

I have activated autobump to smooth out the "artifacts" but that doesn't work.

I use a subdivision of 2 iterations and the type is catclark.

What happens with more iterations? What do the wireframe and normals look like?

>Is this with the sculpting activated?

I just reduced the iterations and rendered.

i guess the 8 iterations was still there when i tried to use an "extreme" value. Is this with the sculpting activated? Because then the artifact occurs.

This is what I get with 3 subdivisions. 8 iterations killed my machine (do you really need that many?).

Hi Lee,

Thanks for responding. More iterations don't seem to work. And i guess the normals are fine :) I think the problem occurs when i use sculpting? I have included the scene file, maybe this will be more of help.

I couldn't upload the HD version of the displacement map because it's around 30mb. I have included a "downgraded" version
