Triplanar projected tex in Bump - Issue

[desire]

Hello!
Can't reach the right settings, using Triplanar projection for image texture (and noise as well) in a Bump channel.
I use tiny Tex Power 0.0015 but in result I get these artefacts you can see in attached pic.
If Coherent Ratio is set to >0 the artefacts in final render become sharper and contrasty
Tell me please who know what I missed?

Thanks in advance.

Hi desire,
the material is assigned to three different parts, but the issue was present only on one mesh. Correcting the uvs of that object, the issue is gone:

Thank you very much bepeg4d for solution and attached scene!
I just thought that the beauty of Triplanar projection is to not worry about UV

Hi desire,
you are welcome
about uvs, yes, unless you choose UVW Mapping or Mesh UV as projection type, in those cases, the uvs are taken into account.
