I'm trying to create a decal which would apply something like a line effect like this:


So I thought I could create a material which would look like this:

and then rotate the decal so it would look transversal.

I'm not sure I should use a texture because I want my decal to always look the same even when scaled up.

But I don't know how to do this.
I can't use WorldPosition, because my lines are always rotated to the same position and they look too big:

What could I use?
