Best way to draw a grid?

Trying to find the best way to daw a Grid. I considered a plane with a grid material or following this tut by creating geomety … https://youtu.be/Q4AOmT9aOEM

No idea which would be the most efficient. Or is there another way? I’m just wanting faint lines a bit like Blender’s grid which also stays the same size when zoomed in.

Would recommend material over all. Don’t go for geometry. I am using a landscape with hex grids rendered by the material. Hex grid is kinda complex compared to squared grid. It is very good for quality and performance, much better then using extra actors. It will be very easy to generate a material for squared grids.

Thanks. Are there any other ways?
