Help with Tri Planar Mapping

I have a large amount of objects of all different sizes and poly counts so I wanted to create a material that will scale correctly with all of them based on world space. It sounded like the Triplanar node should do exactly this unless I am misunderstanding it. However when just using the Triplanar node to map a simple normal texture, I get these strange artifacts

Looks like the texture wrapping mode of the texture might be set to clamp.

Just checked and it is set to repeat.

Is that artifact only on that specific mesh?

Looks like what happens if your mesh has bad normals.
