What could cause this issue, material or mesh?

Hello.

I’m having an issue and I have no idea how to solve this or whats causing it. Is it materials, mesh, lightings?
Anyone know?

It’s a simple material added to a procedurally genereted mesh.

Looks like your UV scale is really small, and you have a texture tiled hundreds of times across the mesh, instead of once or twice.

It sure looks like that’s the issue.
Changing the materials has no effect. Same with lighting.
So, I guess it’s an issue related to the mesh.

Thank you @Scribbler
I will digg into the mesh and see what I can do.
